4.1. Introduction This section is divided into separate subsections some of which cover specific areas within the troubleshooting others describe the overall test facilities in the 2202. But before you jump to any of the subsections you should first consult Section 4.3 which might give you, if not the solution, then some ideas of how to troubleshoot this particular problem of yours. To prevent injury to persons and damage to the Pro Focus be aware of the following: WARNINGs: * Opening the Power Supply can expose live parts. * Any work done on the open instrument with power On must only be done by B-K Medical or their authorized representatives, who are aware of the hazards involved. * Any repair work done on the 2202 system must be followed by an electrical safety test to verify a continuous safe operation of the system. * The Core board contains a lithium battery. The battery must only be replaced by a person having special knowledge as described in sec. 4.2 Replaceable Parts CAUTIONs: * Switch Off the 2202 before connecting or disconnecting the Pro Focus to any peripheral units. Failure to do so could damage the equipment. * The PC Boards in the 2202 are sensitive for static discharge. Therefore, when handling PC Boards always take steps to prevent static discharge - see Section 1.5, Special Tools and Equipment.

4.2. Replaceable Parts Apart from a few exceptions listed below all PC Boards and modules in can be replaced without further actions made. Any work that requires opening the 2202 must however be followed by an electrical safety test. Before replacing a subassembly it is necessary to verify that the ID (revision) of the new part is compatible with the ID of the defective part. Item to be replaced: Type of unit

effected: Necessary action after replacement:

QB0041 Lithium battery All Set system clock, PIN codes

ZN2220 ZN2230 ZN2231

Core Board Assembly / All Set system clock Restore Patient database User settings PIN codes (if new MAC address)

ZD0784 ZD0795

ETX Module All Set system clock + PIN codes (if new MAC address)

UL0041

Hard disk All Restore Patient database, User settings, PIN codes

ZD0757 Back Plane From 1864900 PIN codes


4-4 BI2201-E

4.3. Keys to Troubleshoot Specific Problems (Hints)

4.3.1. Loss of time If you remove the ETX board from the Core board, the time settings will be lost. The same is valid, if you remove the lithium battery on the Core board. Check the lithium battery on the Core board (also check for bad contact).

4.3.2. Transducer or scanner • First of all: Try another transducer! • Try the other Array Input Connector • If possible, connect a single-element transducer to bypass the FE64+ board and the beam

former board. Radial or Vertical lines The problem is most likely caused by the FE64+, Digital beam former, or the transducer.

Concentric rings or Horizontal bands Noise pattern in the B-image A noise pattern in the far field is often caused by external noise entering the scanner trough the air or via the mains cable. To isolate the problem check/try the following: • Connect the scanner to another mains outlet, preferably in another room. A change in the

noise pattern indicates noise on the mains. • Check that the wall outlet has a proper grounding. • Compare different transducer types and frequencies (MFI). External noise is often

frequency specific. Note: Before contacting the support group in Denmark for help with noise problems it is recommended that you try out the suggestions above. Use the image storage facility of the 2202 to save a couple of images showing the problems. The images can be attached to an e-mail.


BI2201-E 4-5

4.4. Service Mode The operative system of the 2202 is Windows XP Embedded. Windows XP Embedded is a componentized version of Windows XP Professional that contains all of the features, functionality, and familiarity of Windows XP Professional. In our case this means that all not needed software, device drivers and other files are removed. This also means that support for non-generic USB storage keys, USB hard disks and USB CD/DVD drive is non-existing. The way Windows XP Embedded is build makes is impossible to install a specific driver after the scanner has left the factory. In this new environment, the usual Windows Desktop has been replaced by the B-K Medical Ultrasound application: Console. This way there is no Windows Desktop behind the application. This is very good when we want to prevent unauthorized access. When we want to get behind the console application, so we have access to Windows, we must switch to Service Mode. In service mode the console-based desktop is replaced by a service menu. Service mode can be activated if you want to: • Upgrade software • Check of Hard Disk • Access Windows Explorer • and other service related issues

4.4.1. Enter Service Mode 1. Start up the scanner and wait for complete boot-up

2. Press ALT + F4 (if you don’t see the below dialog then first click anywhere at the Ultrasound

image field and the press ALT + F4)

3. Enter password: viking

and the scanner will then turn OFF

4.4.10. Update Hardware

The Update Hardware can reprogram the flash memory located on the Core board. Usually this feature is used in connection with software upgrade where e.g. improved functionality can be added to the board as part of the software upgrade. Warning!! If programming the Flash fails then it must be reprogrammed until it succeed otherwise the console application will not work and if you set the scanner to normal mode you will not be able to go back into service mode without reinstalling the hole software (image install). If you have a system with Coreboard ZD0773 version 4 we recommend not to run the Update Hardware!

1. Click on Update Hardware

2. Click on Report Status

3. If the status field contains any “needs update” then click on Program otherwise quit the Coreboard Flash Utility

4.4.11. Event Viewer Event Viewer is the first place to look in for information when you are troubleshooting any problem with your computer. It is used to view events and manage them. There are three categories of events: System, Application and Security events. The System Log records events related to Windows XP system components such as failure of a driver or other system components to load during start up. Usually at start up there is a warning message indicating that a driver or other system component failed, check Event Viewer for more details. The Application Log records events logged by applications, such as errors generated by certain applications. The Security Log records events related to system security. This helps track changes or attempts to break system security.

1. Left click on Event Viewer and select a log to view. The log will appear in the right hand

pane.

2. If you want to look at an event, double click on it. A dialog box will open showing information about what caused the error.

3. You can navigate from error to error in the same log by clicking the up and down arrows.

4. If you need to record an error so you can email it to a technical support person, click on the

button right below the down arrow. This will copy the error to the clipboard. It is now available to be pasted into a text file, you can send to Service at B-K Medical.

5. Close the dialog box when you are done reviewing the event log. Event Viewer displays these types of events:


4-12 BI2201-E

Error: A significant problem, such as loss of data or loss of functionality. For example, if a service fails to load during start-up, an error will be logged. Warning: An event that is not necessarily significant, but may indicate a possible future problem. For example, when disk space is low, a warning will be logged. Information: An event that describes the successful operation of an application, driver, or service. For example, when a network driver loads successfully, an Information event will be logged. Success Audit: An audited security access attempt that succeeds. For example, a user's successful attempt to log on to the system will be logged as a Success Audit event. Failure Audit: An audited security access attempt that fails. For example, if a user tries to access a network drive and fails, the attempt will be logged as a Failure Audit event. Note: Event Viewer is a part of Microsoft Windows XP. Further help can be gained using the Event Viewers built-in help.

4.4.12. Scandisk Scandisk is the program that verifies the logical integrity of a file system on Windows. When Scandisk encounters logical inconsistencies it does not take actions to repair file system data, but let you know that there is problem: Errors found. CHKDSK cannot continue in read-only mode. 1. The scandisk will run automatically in a command prompt box. You are not supposed to

enter anything. When the scandisk has completed, you see this output.

2. Press any key to continue 3. Click on Yes or No depending on the outcome of the test.

4.4.13. Disk Fragment Analyzing and defragmenting disk volumes can help to preserve the performance and general operation of the system. File fragmentation can negatively affect operating system speed and performance. To maintain peak performance when using Windows XP, the condition of your disks should be analyzed on a regular basis - preferably once a year - and defragmentation performed as needed. Note: Prior to running Defrag, you should run a Scandisk to correct any drive errors. Note: Please don’t touch anything running this test, as it may disturb the process. Because defragmenting a disk volume can take a long time (depending on the size of the volume, the number of files, the percentage of fragmentation, and the availability of system resources), you should analyze volumes before defragmenting them, to decide whether or not it is worthwhile to take the time to run the defragmentation process.

How to Analyze a Disk Volume To check for fragmented files and folders on a volume: 1. Click the volume that you want to analyze. 2. Click Analyze to begin the analysis. 3. Review the results of the analysis after it is complete by clicking View Report. If the analysis

tool recommends that the volume be defragmented, follow the steps in the next section. How to Defragment a Disk Volume 1. Click the volume that you want to defragment. 2. Click Defragment to begin the operation.

3. Review the progress of the operation in the Defragmentation Display window. Fragmented

files on the disk appear in red, contiguous files are blue, and system files are green. The goal is to eliminate most of the red in this window.

4.6. HIPAA (Health Insurance Portability and Accountability Act)

4.6.1. Background The American Health Insurance Portability and Accountability Act of 1996 (HIPAA) requires security and privacy of health information. The Privacy Rule is a US federal regulation defining administrative steps, policies, and procedures to safeguard individuals' personal, private health information (protected health information or PHI). The Privacy Rule is designed to empower patients by guaranteeing them access to their medical records, giving them more control over how their PHI is used and disclosed, and providing a clear avenue of recourse if their medical privacy is compromised. The rule is designed to protect medical records and other personal health information maintained by certain health care providers, hospitals, health plans, health insurers and health care clearinghouses. The rule defines "protected health information" as health information that 1. identifies an individual and 2. is maintained or exchanged electronically or in hard copy.


BI2201-E 4-17

If the information has any components that could be used to identify a person, it would be protected. The protection would stay with the information as long as the information is in the hands of a covered entity or a business associate. The protections apply to individually identifiable information in any form, electronic or non-electronic. The paper progeny of electronic information is covered (i.e. the information would not lose its protections simply because it is printed out of a computer), and oral communications are also covered.

4.6.2. Enable patient privacy 1. Start the scanner 2. Click on Setup 3. Click on the System-tab 4. Click on the Password-tab 5. Mark Password Protection Enabled

4.9. How to recover from a crashed main database Console software saves different kind of information in different databases. The main database (2202.mdb) is located in the c:\console\database directory. Databases can crash independently. This mean that you can have a working patient database while you main database is corrupt, so it might be helpful if you start with one database at a time. If you start a scanner and you get an error message with either the word “database” or “jet”, the main database has crashed. Examine the c:\console\database directory in service mode and if you find lock-file 2202.ldb, you must delete it. You can now recover the scanner by copying an empty database from c:\console\database\org to c:\console\database. All settings are now lost, except DICOM settings. Note: If you are able to start scanner and are able to make a “restore to factory” then the effect would be the same as the above.

4.10. How to recover patient database from a crashed system The patient database (PatientDB.mdb) is located in the c:\console\documentation directory. If you experience problems with the archiving system, it could be a corrupt patient database. You can recover the scanner by copying an empty database from c:\console\database to c:\console\documentation. But by doing this all files in the c:\console\documentation directory can not be accessed from the console software any more. The solution is this case is to copy all files to CD’s or DVD’s, and then access them from the archiving system.

4.10.1. Patient Database Recovery tool There is a slight chance for you to recover some part of the patient database if you have a archive CD’s. On the latest archive CD, find the patient database. This patient database can be used to recover. But it must be converted first: 1. Bring scanner to service mode.

The console application MUST NOT be running.

2. Double Click on c:\Console\ PatientDbRecovery.exe.

3. Click on Start.

4. Click on OK.

5. Double click on Start Console on the desktop/or start desktop from the Scanner service menu.

6. Click on View Archive and see if you can find the patients in the record.

Only patients with scans on the hard disk will be found now. All patients you have archived and deleted from the hard disk will not be in the recovered patient database. Finally all scans after the time, the archive CD was created, must be copied to a CD/DVD, as they will not be reachable from the console software.

4.12. How to send log files via email As a new feature the Pro Focus is able to send log files via email to a pre-defined email address. This feature requires: 1. SMTP server available on the network 2. Permission to send email over the network Now, the requirements can only be fulfilled with help from the hospital IT department, as we would be using their SMTP server. Before you continue make sure that these requirements have been fulfilled.

4.12.1. Initialization 1. Bring scanner into service mode

2. Change to networks IP address & net masks according to hospital IT advice.

3. Start Explorer

4. Browse to c:\console.

5. Make a copy of c:\console\console.ini to c:\console\console.ini.org

6. Open c:\console\console.ini (in Notepad).

7. Scroll down to the [Behaviour]-section.

8. Find this line:

;SMTPToAddress=

9. Remove the ; sign and enter the address to receive the log-files here. Fx: [email protected] (This address is fictive.)

10. Scroll down to the [Settings]-section.

11. Find this line: SMTPServer=

12. Enter the name or IP address of the SMTP server here. Fx: SMTPServer=smtpserver.hospital.com (This address is fictive.) or SMTPServer=10.0.0.1 (This address is fictive.)

13. Save this file and exit Notepad.

14. Close Windows Explorer.


4-32 BI2201-E

4.12.2. Verification (or how to use the feature) 1. Start Console

2. Click on Setup

3. Click on the System tab

4. Click on the Version tab

5. Click on the down arrow next to Export and choose Send Log Files as E-mail

6. Enter a comment in the field and click on Export. This comment will be written in the mail

and the log files with be attached to it. (If there is any log file of any kind it will be possible to select the files in the two dropdown lists.)

7. You will then receive an email on the address you provided as the receiver address. Subject of this mail will be "Support call from scanner '<Identification number (MAC address)>'".

4.12.3. Troubleshooting Question: When I click on Send Log Files as E-mail, I get an error message saying: There is

no mail receiver configured (SMTP To-address). What should I do? Answer: Either you did not enter a valid email address, or you forgot to remove the ; sign

from the beginning of the line. Please check your console.ini file to correct the line. Question: When I click on Send Log Files as E-mail, I get an error message saying: Failed to

connect to SMTP server "<name>" (). What should I do? Answer: This means the SMTP server is not valid. You could try to ping it as the first step.

Next step would be to make sure that the SMTP service on the specified server is alive. This can be done by the hospital IT department only.

4.13. How to configure scanner to use an external hard disk to save scans instead of the internal hard disk Many situations demand that you use an external hard disk on the scanner. The support for external hard disk exists already. You can use the external hard disk as an extended USB Flash key to save scans on the hard disk. On the hard disk scans (2D / 3D / cine) are stored in this directory: c:\console\documentation. This folder also contains a patient database (PatientDB.mdb). The database is vital for the archive system to work, as it contains information about patients that has been entered manually or fetched from a Dicom worklist. This patient database also has the links for each of the image-files from the documentation directory. This link is a hard link, which means that the link consists of the partition data, directory data and file name data. A link could look like this: c:\console\documentation\20051114_142222_NoID.bmp. The database is a Microsoft Access database and it has been password protected, so unauthorized access can be prohibited. When the console software is running, the patient database you will be able to see an additional file: PatientDB.ldb. This file is a lock-file for the PatientDB.mdb-file. When the console software is running, you will not be able to copy or view the PatientDB.mdb-file, because of the lock file. When you examine the directory in service mode you may not find this lock-file anymore, but if you do, you can delete it if needed. Next time the console application is started, a new lock file will then be generated. Finally there is a backup of the PatientDB.mdb in the directory as well, but at time being it is useless. If your PatientDB.mdb has crashed, the backup has been damaged as well. (We are looking into this). The standard solution when you use the external hard disk as an extended USB flash key does not save the patient database on the hard disk. The tweak below makes it possible to save the patient database to the external hard disk as well. More precisely this tweak will make the c:\console\documentation directory almost obsolete. Here is the procedure on to get it work. (If you are not sure about what you are doing, please do not continue. A mistake could make the scanner unstable.) Your external hard disk has been partitioned (NTFS) and formatted before you plug it into the scanner. Only external hard disk types supported by the scanner will work. 1. Bring the scanner into service mode

2. Connect you external hard disk and wait for approx 2 min.

3. Right click on My Computer and select Manage

4. Click on Disk Management

5. Examine in the right side on the window that the external hard disk has been found. If you do not see the external hard disk either it’s not working properly or it’s not supported. Do not continue if you do not find your external hard disk in the window.

6. Make sure that the DVD drive has drive letter D.


4-34 BI2201-E

7. Now select your external hard disk and make sure that it has NOT any of these drive letters: A, B, C, D, E. (E is reserved for the USB flash key, so even if the USB flash key is not connected, we still want to keep the reservation.)

8. Exit Disk Management

9. Double click on explorer

10. Navigate to your external hard disk

11. Make a directory (fx Documentation). (You can use the root of you external hard disk, as this will not work).

12. Navigate to the c:\console directory

13. Make a backup of the console.ini file

14. Edit the console.ini file

15. Find this section: [Paths]

16. Make a new line just below this line: ;;;;Path for documentation directory

17. Write this in the new blank line: DocumentationDirPath1=<drive letter>:\<directory> (In my case I wrote:

DocumentationDirPath1=F:\Documentation, as my external hard disk had drive letter F, and my directory was called Documentation.)

18. Save console.ini

19. Start console (from service mode)

20. Create a test patient and save a couple of images

21. Switch back to explorer and examine that you find the scans and the patient database on

your external hard disk. Default behavior for console software is that it would look in the console.ini file for the documentation paths. First it will look DocumentationDirPath1, if this is not available, it will look for DocumentationDirPath2. Default values for DocumentationDirPath1 is q:\documentation and for DocumentationDirPath2 is c:\console\documentation. This works out as a safety line for this tweak. In case the external hard disk is not connected, console software will use the second path. If the console software does not find a patient database, a new empty one will be created. It can be confusing having two different patient databases and two different set of images etc.

4.13.1. How to configure scanner to use a network drive It is possible to configure scanner to use a network drive to archive examinations. There are 3 steps in this configuration. 1. Configure Microsoft Windows-based PC 2. Configure Network 3. Configure Scanner

4.13.1.1. Configure Microsoft Windows-based PC Configuration of Microsoft Windows-based PC is a very big topic. Bottom-line is that we need a shared folder on the hard drive, where scanner can save files. Basic step for a Microsoft Windows XP: 1. Start Explorer 2. Create a folder on your hard drive.

Make sure you have enough space.

3. Right click on the folder and select Sharing and security…

4. Select Share this folder

5. Enter a Share name as the field will now be available.

6. Click on Permissions as the button is also available now.

7. Make sure the user have Change rights.

8. Click on OK to close Permission Pop up 9. Click on OK


4-36 BI2201-E

4.13.1.2.

4.13.1.3.

Configure Network You can connect the Microsoft Windows-based PC and the scanner different way. It’s not the scope of this document to cover that. Main idea is that you need to configure network for the Microsoft Windows-based PC first. Then configure network on the scanner. This can be done by entering Service mode, if Dicom is not available on the scanner. Just make sure the network connection between scanner and PC is working.

Configure Scanner Click on Customize, System and then Network Drive

Enter the UNC path in the field. The UNC path is the path to the folder you created in the first step. So fx. If your PC has this IP Address: 192.168.1.10 and the folder name is 2202 then you enter this: \\192.168.1.10\2202 Now enter username and password for the user that is allowed to save files in the folder created in the first step. If you are on a Domain you may have to write the username like this: Domain\username. (eg bkmed\sla, where bkmed is our domain name and sla is my username.) Click on Test Connection to test the connection. A success full test looks like this:

A failing test will keep asking for a correct set of username/password: When you have success fully tested the connection, click on Close. (Click on Yes to save, if asked.)

4.13.2. How to transfer file from one hard disk to another If the scanner hard disk crashes du to Microsoft Windows or the console application, in most cases, you are able to rescue the images. First you should read chapter 4.9 and chapter Error! Reference source not found.. There are two easy ways to transfer file from one hard disk to another. First one needs to realize which files are going to be transferred. Usually we are interested in the particularly this directory: c:\console\documentation, as all exams and the patient database is stored in this directory. Both of the ways require special tools. None of these parts are sold by B-K Medical. You must buy them at your local store.

a. IDE (44 pins) to USB adapter b. Dual connector IDE (44 pin) cable + 1 jumper

This adapter can be bought in many different types. This is just one of them.

The dual connector IDE (44-pins) cable is needed.

You actually only need 1 jumper.

4.13.3. Using IDE (44 pins) to USB adapter 1. You must replace the scanner hard disk first. 2. Then you must start the scanner and see that everything is working perfect. 3. Bring the scanner into service mode

4. Now you take the old hard disk and mount it on the adapter and connect the adapter to

the USB connector (using the cable coming with the adapter).

5. Wait until Windows has found the hardware and the hardware is ready to be used.

6. Start Windows Explorer and use the hard disk (which now is your USB hard disk)

Con’s Pro’s 1. On the first core boards ZD0773 the USB

standard is 1.1. This gives a very limited transfer speed.

2. Not all the adapters will be detected by Windows. If your adapter is not detected, only way out is to replace it.

1. On the latest core boards ZD0773 the USB standard is 2.0. This gives a very high transfer speed.

2. It’s more convenient to work with. 3. You can use the adapter to connect the hard

disk almost everywhere.


4-38 BI2201-E

4.13.4. Using dual connector IDE (44 pins) Cable 1. You must dismantle the scanner. 2. Take out the core board assembly. 3. Remove the hard disk and the cable. 4. Connect the dual connector cable. 5. Insert carefully the core board assembly in the cassette. 6. Connect the new hard disk as Device 0 7. Connect the old hard disk as Device 1. 8. Put on the jumper as shown on the picture on the hard disk. 9. Then you must start the scanner and see that everything is working perfect. 10. Bring the scanner into service mode 11. Start Windows Explorer and use the hard disk.

Con’s Pro’s 1. It’s not convenient to work with. 2. You must assemble and disassemble a

couple of time

1. Transfer speed is very high, as the IDE bus is being used.

4.14. Software Structure In this chapter we will look at the directory structure and then on some of the important files. The hard disk has been partitioned into one single partition. This is mapped to drive letter C. The CD drive has been mapped to drive letter D. Drive letter E is reserved for an optional USB flash key.

4.14.1. Directory Structure of hard disk (C-drive) Some of the directories and files are Microsoft Windows standard. These will not be addressed any further here. The important directories have been highlighted in the image above. We will in the following concentrate on these five directories.

4.14.1.1.

4.14.1.2.

CasaEngine All hardware configuration files are located in this directory. There are two sub directories.

Console This is the main software directory. There are 10 subdirectories which all require a short presentation. In the console directory you find the important console.ini file, which is the software configuration file.

Bodymarks Each of the body marks is represented by an image file. The default naming policy is bodym_<number>.bmp (fx. Bodym_001.bmp). If you find any files which do not follow the above rule, they are custom made. In case of file rescuing these might be needed.

CasaWare This directory includes supporting software for the console application.


4-40 BI2201-E

Codec, Lagarith In this directory you can the find the Lagarith Codec. This codec is used in the Cine clips. First time you want to view a clip on a PC, you must install the codec. This directory is copied to the CD every time you copy exams (depending on your configuration.)

Database This is a very important directory, as (almost) all databases are stored here. The main database is 2202.mdb. Then there is the backup of this file: 2202_backup.mdb. The Dicom setup is stored in DICOMSetupDB.mdb. PatientDB.mdb is blank copy of the patient database. The sub directory org contains an empty 2202.mdb

Documentation This is where all exams are stored. All 3D scans, all US images and all clips. Furthermore you find the actual patient database PatientDB.mdb and a backup of this here.

Report Files needed to create a report printout are stored here.

StagingArea This is the staging area directory. All exams that have been ordered to burn on a CD will be here until the CD has been burned. Then this directory will be empty. If you have something in this directory, each time the console application starts you will see a message about it.

Dicom This directory stores both the Dicom program files as well as links to documents that are being send to a Dicom device.


BI2201-E 4-41

4.14.1.3. XPE_Backup This directory is important after software upgrade. If you make a clean installation, this directory is not used. Inside this directory a collection of different files can be found. These are copied from different places on the hard disk. Here is the directory listening:

File / Directory name Comment Copied from 2202.mdb Main setup database C:\Console\Database Console.ini Main configuration file C:\Console Lbk.bin License File C:\ PatientDB.mdb Empty Template C:\Console\Database Viking.ini Actual configuration C:\ Bodymarks [DIR] All bodymarks C:\Console Documentation [DIR] All patient scans and

Patient database C:\Console

4.15. How to access the content of the CD in the CD-drive from Windows Explorer in service mode It’s not possible to read the content of the CD in the CD-drive in Windows Explorer, due to some Microsoft setting. You can access the content using a Command Prompt.

4.16. There is no Recordable CD Drive Somehow Windows could not recognize the CD drive as a recordable CD drive. We must make Windows use the correct driver for the drive. 1. Start scanner in service mode 2. Remove all USB flash keys (only the CD should remain) 3. Open Device Manager (icon on right top of screen)

4. Select DVD/CD-ROM drives 5. Click on the CD-rom device (without any brand name) and click on Action and then

Uninstall

6. Click on OK. 7. Select DVD/CD-ROM drives

CD-Rom drive


4-42 BI2201-E

8. Click on Action and select "Scan for hardware changes" 9. Examine the CD-drive. It should be: fx. TEAC DW-224E-C USB Device

10. Exit Device Manager

4.17. How to make your own BIOS plug EL1011

The BIOS plug EL1011 is used in the 2202 keyboard whenever BIOS access is needed. The plug short circuits pin 5 & 6 on the RJ 12 connector in the keyboard.

4.17.1. Tools Required

• 1 pcs RJ12 6/6 line plug (Farnell no. 106309

• 4 cm cable 26 AWG (used in 100Mb LAN cable)

• Tool for RJ12 (Paladin Tools 1302)

4.17.2. Assembly Procedure On the RJ12 plug short Pin 5 and Pin 6 with the 4 cm 26 AWG cable. Use the crimping tool to fasten the cable.


BI2201-E 4-43

4.18. License Codes The software options on the scanner are controlled by a license enabling a specific option. The license(s) are kept in a file on the hard disk. The license combined with the Scanner Identity which is a unique number for each scanner opens up for the option so a specific license will only work on one scanner. The license(s) and Scanner Identity can be found under Customize - System - License. The scanner identification is the MAC address of the ETX board on scanners with serial no. below 1864900. Scanners with a higher serial no. have the serial number programmed into the Backplane board so the scanner identification is the serial no. in Mac address format. This means that if changing the EXT board or Core board assembly in a scanner with a serial no. below 1864900 then new licenses have to be entered. If replacing a backplane board in a scanner with serial no higher than 1864900 then the MAC address will be the new Scanner Identification unless the back plane board has been preprogrammed from the factory. If installing a hard disk from another scanner then the license will be inactive because the Scanner Identification does not match. In that case the licenses have to be changed using the license CD that came with the system see 4.18.1 or by re-entering the license(s) manually. If entering the license manually then the file C:\LBK.BIN must be deleted first. Licenses cannot be entered on a system which has one or more invalid licenses in the LBK.BIN file. If the LBK.BIN file contains an invalid license then all licenses will become invalid and the scanner will behave as a Blue Pro Focus without any options enabled. Note! The “Delete License” is only for demo licenses and not permanent licenses.

4.18.1. Install License Codes from the Back-up CD

Note! Changing the time and date after the licenses has been applied may result in deactivation of the license(s)

4.19. Power Supply Trouble shooting

4.19.1. Introduction The Power Supply On/Off control is placed on the Core board so if you have a problem starting up the Power Supply it could be the Power Supply itself or the Core board. Note : A number of things on the Core board Assembly could result in start up problems (Core board it self, Lithium battery being completely flat, defective EXT board)

4.19.2. LED indicators on the Power Supply There are some LED’s on the Power Supply indicating the status of it. If you look behind the holes near the mains input connector you will find 3 green LEDs. These should all be lit when the system is turned on. Further inside the Power Supply you find a green and a Yellow LED. These can be difficult to see as you have to look through a hole in the PCB that is placed above the LEDs, see the below drawing. The Green LED is the 5V standby voltage and this should be on whenever mains are fed to the Power Supply. The Yellow Led indicates that the system is OFF but has previously been turned ON.


BI2201-E 4-45

4.19.3. Steps to test the Power Supply 1. Check that the Green 5V Standby is lit. If not check mains supply and fuses

2. When pressing the Power ON switch on the front of the scanner do you then

hear any reaction from the Power Supply (Fans starts running, light in the 3 Green LEDs, Light in the Power ON switch). If not first remove the mains for 1 minute and the reconnect it and try turning on the scanner again - if that does not help check the Power ON Switch and also check the voltage on the Lithium Battery on the Core board

3. Test the Power Supply as described in 4.19.4

4.19.4. How to test the Power Supply ZG0346 as standalone In section 9, chapter 3 you find the power supply connector diagram. The power supply behaves just like a PC ATX Power supply, but provides additional voltages. In the stores you can find different PC power supply testers. We have tested a product from Coolmax: PS-124. (http://www.coolmaxusa.com/powertester.asp?item=powertester). This product is a simple tester for switching power supply. It makes it easy to test the power supply output. (This is not an advertisement for Coolmax. We do not sell this product, so you have to buy it or some other equivalent from your local store.) Next step is to create connector cable, as the pin layouts of the ZG0346 connector are not direct mapped to the pin layouts of the tester. Using the table, you make the “24-pins to 20-pins adapter” cable. Please use AWG 16 and AWG 20 cables.

5V Standby OK

When your adapter cable is ready, you can make the test: 1. Plug in your 24-pins “24-pins to 20-pins adapter” connector to tester

2. Plug in your 20-pins “24-pins to 20-pins adapter” connector to the power supply ZG0346

3. Connect the power cord to the power supply

4. Turn on the power switch in the wall outlet.

5. Check LED lights on the tester: (+5V. +12V. +3.3V. +5VBS. PG)

• If the power output is working, the LED will light and you will hear a sound • If the power output fails, you won't see the LED light & no sound

6. Turn off the power switch in the wall outlet.

7. Remove the connectors Warning: This tester is designed only for power supply output tests. Do not leave it connected to the power supply unattended. It generates heat and could possibly damage your power supply. The pin layout for a standard ATX power connector looks like this:

5.4. Adjusting the Brightness of the Screen

Your scanner may be used with different levels of room lighting. Whenever the lighting changes significantly, you should recalibrate the screen brightness. To calibrate the screen brightness: 1. Freeze the image.

2. Press ALT+SHIFT+G on the keyboard. A series of gray bars appears on a

black background.

3. Use the contrast button on the monitor to adjust the bars so that the 100% bar is bright white and the 90% to 10% bars seem to decrease progressively in brightness.

4. Use the brightness button on the monitor to increase the brightness until the 1%, 2% and 3% bars (above the 10% bar) become visible.

5. Use the brightness button to decrease the brightness until the background becomes black and the 1% bar just disappears.

5.5. Adjusting the Reading Lights After you have turned on the scanner, you can adjust the brightness of the 3 small "lamps" under the CD drive - the Reading Lights. To adjust the reading light brightness: Click Light under Image on the right side of the screen and drag the slider (or point at Light and press [+/-]).

Theory of Operation System Pro Focus 2202

8-2 BI2201-E

8.1. Introduction This section describes the theory of operation of the Diagnostic Ultrasound System 2202. The description is divided into two separate sub-sections: General Description Supported by a complete block diagram, this section aims to give you an understanding of the interaction between modules, Boards and major function blocks. It explains briefly the main signal flow through the 2202 system. Board Description This section provides an overall description of each Board, explaining the main function of the function blocks on the board.

8.2. General Description

The basic hardware architecture consists of three active PCBs connected to a passive backplane. The active boards are: 1. A 64-channel analog Front End (FE) board with transmitters, 3 array transducer

connectors, relays, receivers, Harmonic Imaging filters, and TGC amplifiers. 2. A 64-channel Digital Beam former (DBF) with signal conditioning circuitry and

A/D converter per channel and 16 beam former ASICs plus control logic and profile memory.

3. A Core board with real-time scan controller, vector processor, Doppler system

and scan converter/display system. Further, an industry standard PC module and a hard disk drive is attached to the Core board.

Several other units connect to the Backplane. These are: • Power Supply • CD-RW Disk Drive* • Single Element Transducer Module** (field option) • Mover Control Module** for 3D application (field option) • Keyboard assembly • Foot switch (accessory) • Internal speakers* * Connects through a hub. ** The Single Element and Mover Control Modules connect to the Backplane via an interface board. The Core board interfaces to an Analog Video Interface Board (AVIB) with all video and graphics i/o, including the main monitor output. The keyboard is a self-contained unit including keys, track ball, gain dials, TGC potentiometers and a small keyboard controller which interfaces to the built-in PC via a single USB serial interface.

Fig. 8.2-2 - FE64+ Block Diagram Transducer Connectors: Three 260 pole ZIF CANNON connectors for array probes. Xmit Timing (XMIT RAM & Dig. Rotate): 32 channels transmit timing control with the option for pulse width apodization for controlling the transmit beam profile. The beam profile is unfolded and rotated digitally, and the 64 output channels (bits) drive the bipolar transmitters of the 2202. Transmitters: 64 bipolar current driving transmitters. Output regulation is common to all channels, individual channel apodization may be achieved by pulse width modulation. In CW mode, the output stages are supplied by ±12V instead of the ±HV supply in order to reduce power dissipation. HVMUX: High voltage switches for connecting the 64-channel element bus to the 192 transducer elements. The switches are normally reprogrammed in the time interval between receive end and transmit start, but may also be reprogrammed immediately after transmit end to support synthetic aperture. Relays: 384 bi-stable switches for connecting the element bus to one of three array transducer connectors. Receiver: 64 low-noise preamplifiers with 19dB gain. These are followed by selectable high-pass filters for improved Harmonic Imaging. TGC: 64 TGC amplifiers which handles the first 0 to 48dB TGC gain. Each outputs a differential voltage signal, which is converted into a single ended current output in the transconductance output stage. There is an additional digital TGC gain stage in the Vector Processor on the Core board.

Fig. 8.2-3 - DBF Block Diagram Channel Conditioning: 64 input channel strips. Each consists of a current mode receiver, an anti-aliasing filter bank, a filter select switch and a buffer amplifier. A/D Converters: 64 10-bit pipelined ADCs capable of 60Msps conversion. The inputs to the ADCs are AC-coupled (TBD). The outputs are fed to the digital beam former ASICs. Beam former ASICs: 16 Analogic ASICs, each processing four channels with 1, 2 or 4 beams per channel. The ASICs dynamically apply individual delay and apodization to each channel. Profile Memory & Control: Local SDRAM bank for storing the receive profiles needed by the ASICs to process data. The controller FPGA provides host access for uploading the memory, even during scanning, and handles the dynamic download of parameters from memory to the ASICs during scanning. To minimize download time (and increase PRF), all 16 ASICs are loaded in parallel, so the memory is 192 bits wide.

Fig. 8.2-5 - Core Board RTSC Sub-system

The RTSC takes care of the hard real-time tasks in the scanner. A local processor (Sharc DSP) is located here to perform a number of tasks: • Calculation of beam profiles for the DBF • Communication with the Embedded PC host processor • Dynamic transfer of parameters to the FE and DBF during scanning • Dynamic transfer of parameters to VECP, DOP and SCON sub-systems during

scanning • Interfacing to the ECG Module • SPI communication with the transducers and


BI2201-E 8-7

• Configuration of FPGAs during boot.

A Host Interface provides a memory area, which is shared between the Embedded PC and the Sharc DSP; it is through this memory only that they communicate and exchange data. The Sequencer part of the RTSC generates all timing signals for the acquisition of ultrasound data to the FE and DBF and also internally to VECP, DOP and SCON. It also contains the physical backplane interface to the front-end boards (FE, SEMIF and DBF). Finally, a master clock generator provides all system clocks (except for the Embedded PC), both fixed and variable. The variable clock frequency is determined by the Sequencer (ultimately controlled by the Sharc DSP).

Fig. 8.2-6 - Core Board VECP and DOP Sub-systems

The Vector Processor performs down-conversion, envelope detection, dynamic range compression, sampling frequency conversion and image enhancement on RF data from the Beam Former. The signal is then delivered to the Scan Converter. In Doppler modes, the VECP delivers a down-converted signal to the Doppler module. Doppler (DOP): The Doppler module comprises the two flow detection modules: Spectral Doppler and CFM, see Fig. 8.2-6. The Spectral Doppler is a CW/PW Doppler system. A Floating-point DSP performs FFT on a time signal from one volume element and outputs a spectrogram to the Scan Converter. The Doppler signal is also output as a stereo audio signal. The processing includes: 1. Input from the Doppler Input Buffer. 2. Wall Filter for removing low frequency tissue-generated motion artifacts. 3. Missing Signal Estimation in block interleaved duplex/triplex modes. 4. FFT: motion detection. 5. Real Time Curves: statistical values for each spectrum (min, mean, max). 6. Audio output. 7. Motion Noise Cancellation: removing transducer movement artifacts. 8. Output to the Scan Converter


8-8 BI2201-E

The CFM module maps flow in a section of the scanned area. It processes input data up to a rate of 2.5M CFM cells/second. Output data are velocity, variance and power. Velocity and variance or velocity and power can be combined in one image. The CFM processing includes: 1. Input from the CFM Input Buffer 2. Wall Filter for removing low frequency tissue-generated motion artifacts. 3. Correlation: motion detection. 4. Signal power detection. 5. Parameter extraction in look-up tables. 6. Median Filtering for reducing image noise. 7. Discrimination: eliminating tissue motion artifacts. 8. Output to the Scan Converter.

The SCON is integrated and implemented in a single FPGA. It has the same functionality, but given the general physical implementation, see Fig. 8.2-7, it can be changed (even radically) later without changes to the Core board itself. The SCON comprises a frame averaging function with an Image Review Buffer for a large amount of frames (64MBytes), a Scan Line Buffer, and a Scan Processor function, which works in tandem with B-K’s coordinate transformation ASIC. The converted images are buffered in the Display Memory from which they are transferred to the VIME through a color look-up table.

BI2201-E 8-9

The VIME sub-system receives image streams from the Embedded PC, the SCON and from external video equipment and merges the streams together, de-interlacing the video input on the way, for display on the main monitor. This merging includes scaling of either SCON or external video for picture-in-picture function. The Embedded PC sets a window size and a transparency color for each of the images in order to define the overlay priority. The VIME system also captures the merged frames, thus allowing the Embedded PC to access screen snapshots or real-time sequences and transfer them to documentation units such as disk drives, DICOM or digital VCRs. It also captures SCON images for the benefit of the 3D application.

Fig. 8.2-9 - Core Board Embedded PC Sub-system The Embedded PC runs the user application and generally controls the entire scanner. It is an off-the-shelf module with an 1400MHz Pentium M processor, chipset, memory, etc. The Embedded PC interfaces physically to the Core board through high density connectors, no cables. A PCI-to-Local Bus bridge interfaces the PC module’s PCI bus to the Core board hardware. The Embedded PC further provides two USB ports and two COM ports for attaching external devices and a parallel port for an internal boundary scan chain. Hubs are provided for increasing the number of USB connections and an additional COM port. An IDE interface connects to a 2.5” HDD, which is also mounted on the Core board. This disk holds the operating system (embedded Windows XP), the firmware configuration files and the ultrasound application files. An audio codec is used as a combined DAC/switch to convert the digital audio from the Doppler FFT and select between FFT audio and audio from an external source, typically a VCR. The audio output goes to a 2W power amplifier in the HUB module. Finally, the module includes an Atmel AVR microcontroller, which serves as an I2C bridge; it translates RS-232 commands from the Embedded PC to four I2C system busses. The AVR may also poll the various temperature sensors in the system and control the PSU fans for optimal noise reduction.

8.3.4. Analog Video Interface Board, AVIB

The AVIB connects to the Core board and provides the interface for connection of system monitor as well as miscellaneous video equipment. The physical connectors are placed on a separate board, the AVCON (see Section 8.3.5).

Video DAC: Triple DAC for conversion of digital RGB stream to analog (S)VGA. Digital Video Encoder: Translates (a selected part of) the non-interlaced digital output from the VIME sub-system on the Core board into interlaced RGB for viewing on a TV monitor. Analog Video Encoder: Translates the interlaced RGB output from the Digital Video Encoder into S-video and CVBS for connection of analog VCRs, video printers and low-end TV monitors. Digital Video Decoder: Converts incoming S-video and CVBS signals to digital component video as input to the VIME sub-system on the Core board. Video ADC: Triple ADC for conversion of analog RGB input to digital component video as input to the VIME sub-system on the Core board.

8.3.5. Analog Video Connector Board, AVCON The AVCON board contains all connectors for audio and video I/O. It interfaces to the AVIB. There are no active components on the board.


BI2201-E 8-11

8.3.6. USB Hub, HUB The USB hub board provides the two front USB connectors as well as the USB interface to the CD-RW unit, see below. A single USB connects the Backplane to the hub board. A separate power cable is also provided which includes 12V for the CD-RW unit; the 500mA limit of USB 5V power is insufficient. Due to the placement of the internal speakers, the Hub Board also contains a 2W class-D audio amplifier. In this way, the speaker wires can be kept very short, and an output filter is not required.

8.3.7. External Devices External devices are part of the scanner and can be mounted directly on the central scanner unit (also known as the Engine) containing the main PCBs and Power Supply. However, they may also be placed away from it at places convenient to the user. Keyboard Assembly: Assembly consisting of an alphanumeric keyboard, a pointing device (track ball), and an ultrasound control panel with dedicated keys, gain dials and TGC slide potentiometers. A microcontroller handles the key scanning, gain dial decoding and A/D conversion of the TGC pots. A USB hub in the keyboard connects the various modules and provides a single USB connection to the Embedded PC. Monitor: A standard 15" SVGA CRT or 17” flat panel monitor. Mass Storage: CD-RW with USB interface. Power supply (non removable): The power supply is a SMPS type. Four isolated outlets for external equipment are provided. One is allocated for the monitor and one for a built-in video printer. The unit supplies 3.3VD, 5VD, 12VD, ±5VA, ±12VA, ±HVMUX, ±HV. The HV output for the transmitters is not programmable. A standard ATX handshake allows the Windows© powered PC to control start-up and shut-down. The unit also contains circuitry for controlling the two fans below the card cage and its own fan.

8.3.8. Optional Devices Other devices may be connected. An accessory is a device, which the customer can purchase and use without further requirements. It attaches to an external connector. A field option is a device or module, which a customer purchases after the scanner, but it may only be installed inside the scanner by service personnel. Foot Switch (accessory): Existing foot switch UA1215 or a similar one with three pedals (B-K Number TBD), which is recommended for use with the 3D application. The foot switch is attached to the Backplane (rear panel). Some pedal functions are user programmable. Palm Control Unit (accessory): Existing Palm Control Unit UA1270. Connects to the Backplane (COM1 on the rear panel) using existing adapter UA1271. Requires a 5VDC supply of 100mA. Magnetic Tracking Freehand (accessory): Existing MTF Upgrade kit UA0576, can be connected to the Backplane (rear panel) COM1 port.


8-12 BI2201-E

Single Element Module, SEM (field option): Existing SEM, ZH0651. A separate module with motor control, transmitter, receiver, TGC and transducer code identification. Connects internally to the SEMIF. SEM Interface, SEMIF (field option): Must be installed with the SEM and MCM options. Contains a 14-bit ADC in order to interface the analog output from the SEM to the digital input port of the VECP and a TGC “splitter” circuit for generating the two TGC control voltages for the SEM. There is also a USB-to-RS232 converter for the MCM. Connects internally to the Backplane. Mover Control Module, MCM (field option): Existing MCM, consisting of modules ZH0752/53/54 or a new compatible single-board solution. Controls the external mover units UA0550/51/52. Connects internally to the SEMIF. Whenever both SEM and MCM are installed, the control signals from the MCM are connected to the transducer LEMO connector in the SEM so that seamless integration with 205x transducers is possible. Additionally, it will be possible to connect USB based drive types to the external USB ports, provided that drivers are included in the embedded operating system.
