Supported Displays

All diagnostic and clinical Image Systems displays

Most clinical non-Image Systems displays connected to a NVIDIA Quadro or NVS series

graphics card via a DVI-D Dual-Link cable, or via DisplayPort.

Note: The recently introduced N-Series displays (2016) use a 24-volt external power supply.

Older P-Series and M-Series monitors use 12-volt external power supplies. Use care not to

interchange power supplies as non-warranty damage could result!

In addition, on displays with an external power supply, check the orientation of the connector

as shown below:

Supported Graphics Cards NVIDIA Quadro/FX or NVS series

ATI FirePro, FireGL, FireMV series with two DVI ports

*We do not recommend/support mixing of AMD/ATI and nVidia graphics cards and drivers within the

same workstation.

NOTE: Displays using a DVI connection must be connected with DVI-D Dual-Link cables. Not all

NVIDIA or ATI graphics cards and drivers are supported. The supported displays and

graphics cards list continues to expand and are available for download on the Richardson

Electronics Healthcare TEKLink website. Contact your Richardson Electronics Healthcare

sales or support representative for current compatibility.

Recommended Windows Settings

Screen Saver All LCD displays will exhibit some “image retention” when an image is left on the screen for a

period of time. This is easily remedied by implementing the Windows Screen saver function. A

moving image such as “Mystify” with a setting of 10 to 15 minutes is recommended.

Windows 7 - Click on the Start menu orb, select Control Panel, click the Personalization

icon, and choose the Screen Saver icon.

Windows XP – Click on the Start menu, select Settings, select Control Panel, double-click

the Display icon, and select the Screen Saver tab.

Display Power Management System (DPMS)

To extend the life the backlight the Windows DPMS function is encouraged. A setting from 20

to 60 minutes is recommended.

Windows 7 – Navigate to the Screen Saver settings, click the “Change power settings”

link, click the “Change plan settings” link, and select the desired power management

settings.

Windows XP – Navigate to the Screen Saver settings, click the Power button, and select

the desired power management settings.

Desktop Wallpaper

To minimize “image retention” issues, setting the Desktop Wallpaper to “none” is

recommended.

Windows 7 - Click on the Start menu orb, select Control Panel, click the Personalization

icon, and click the “Desktop Background” link.

Windows XP – Click on the Start menu, select Settings, select Control Panel, double-click

the Display icon, and select the Desktop tab.

Remote Desktop Remote Desktop applications may load a different display driver that could affect the way that

CFS communicates with the displays. If this occurs, reboot the workstation to restore the

correct NVidia drivers.


CFS Installation

NOTE: Before starting this install process: Install and configure video drivers and card(s)

for all grayscale and color monitors. Richardson Electronics Healthcare highly

recommends using video drivers supplied on the CD shipped with all Image Systems

displays.

1. Log into computer with Administrator rights.

2. Insert the Richardson Electronics Healthcare software CD labeled “Image Systems” into the

CD/DVD drive.

3. Select “Install CFS Local”.

.4 Right click on the install file in the window that opens and select “Run as administrator”.

5. Follow the on-screen instructions.

By default, the installer will run until completed with no user interaction needed. The installer

gives the user the ability to step through the install process by changing the ‘Run’ radio button to

‘Step’.

Using a Calibration Photometer The CFS Software supports X-Rite Chroma 5 or X-Rite I1D3 Photometers, and will

automatically detect the connected photometer.

The i1D3 is HID-Compliant and thus does NOT require any external drivers to be installed.

The i1D3 can measure ambient light with the diffuser in place. An internal sensor is used to

detect the position of the diffuser and alert the user if the diffuser is in the wrong position.

Luminance sampling using either photometer is available on the CFS Icon Pop-up menu.

NOTE: BEFORE unplugging the Image Systems calibration puck it is recommended that you

click on the “Safely Remove Hardware” icon in the System tool tray and “stop” the

“Sequel Imaging Chroma Calibrator” device.

NOTE: X-Rite I1 Display photometers are HID-Compliant and use USB drivers that are already

included in Windows.


Opening CFS

CFS Dialog Box

After proper installation of your CFS software, the CFS icon will appear in the System tool

tray. After initial install it may take several minutes for the CFS icon to appear. Double-click

“ISC CFS” in the System Tray (System Tray is usually located in the lower right corner of

desktop).

ISC CFS System Tray Icon


CFS Pop-up Menu

When the CFS dialog box is minimized several other CFS features can be accessed with a

right mouse click on the ISC CFS icon in the tool tray (see picture below).

Shutdown CFS

Click Shutdown CFS to stop the CFS Application. Please be aware that this will

terminate all monitoring and calibration operations!

Restart CFS

Clicking Restart CFS will stop the current instance of CFS and re-launch the program.

Uninstall CFS

Clicking Uninstall CFS will remove the application from Windows. The calibration data, event

log files, and status reports will remain in the C:\Image Systems directory after uninstall is

completed. These can be completely removed by deleting the Image Systems directory.

Factory Reset

Selecting Factory Reset launches a window that allows the user to select the display to

perform a Factory Reset on.

Check the box to delete the panel data that is

stored on the workstation. CFS will then

download the factory settings from the panel

when the Reset button is pressed.

Note: For A-Series and M-Series displays a

photometer will be required to recalibrate the

display.

Display Properties

This is a link to the Windows Display Properties,

Settings tab. If changes are made to the

display(s) configuration, CFS will automatically

detect the changes.


Visual Acceptance

Selecting “Visual Acceptance” will initiate the test(s) indicated on the Preferences tab. This

test can also be automatically run at specified times indicated on the Scheduler tab.

Test Patterns

Selecting “Test Patterns” will display a SMPTE test pattern or the last user selected pattern on

all displays. Right-click anywhere on the screen to select other test patterns or functions.

Select “Exit” to return to normal mode.

PinPoint

Selecting “PinPoint” isolates a region of interest by dimming all screens leaving a high

contrast window centered on the mouse pointer. This area can also be magnified using the

scroll wheel or the arrow keys. Click the right mouse button or the Esc key to return to

normal mode. More details can be found in the Preferences tab section.

Uniformity Test

Uniformity measurements to the TG18 and DIN standards are possible with CFS using an

Image Systems hand held USB photometer (puck). Plug the USB puck into a USB port and

right click on the CFS icon in the tool tray. Select Uniformity and then the desired uniformity

check (i.e. IS 100%). Follow the on screen instructions. The results of each test are displayed

on the screen and recorded. The data can be viewed and printed by running a Uniformity

report from the Reports tab.

Low Contrast Spot Test

This test can be performed by an end-user with no additional special tools. An additional

advantage of this test is that it takes into account not only the DICOM 3.14 calibration as

performed by CFS, but it also takes into account the ambient lighting in the environment, any

modifications to brightness and other settings on the display, and the perception of the

eye/brain of the end-user. Since this is an easy test to access and perform at any time, it is

recommended that this test be performed frequently, such as at the beginning of every sign-

on to the device, or any time a significant change in ambient lighting occurs.

The test can be accessed by right clicking the CFS icon in system tool tray, selecting Low

Contrast Spot Test, and then either the "Quick Test" or the "Multi Background" test.

Quick Test - Consists of a single low

contrast disc randomly positioned on the

display.

Multi Background – Consists of three

different test images, each image consists of

a single randomly located disc at different

background luminance levels.

The test is successful when the user is able to

visually locate the randomly placed disc on

the display, position the mouse pointer over

the disc, and then left click the mouse to

acknowledge the location. If the test is

unsuccessful, then the user may need to

adjust ambient lighting conditions, display settings, or request support.


Luminance Sampling

Luminance sampling is possible with CFS using an Image Systems USB photometer. Plug the

photometer into a USB port and right click on the CFS icon in the tool tray. Select Luminance

Sampling, then Continuous Automatic.

When the user selects Continuous Automatic, the Luminance Sampler dialog box is displayed.

The sampling mode has 3 options:

Paused (not sampling)

Capture single sample

Sample continuously at selectable intervals

When a sample is taken the Luminance parameters are displayed as shown below:


Quick CFS Set-up / Calibration (Displays with integrated front sensors)

1. Double-click ISC CFS Dialog icon in

Low Level Offset Change this setting to adjust for ambient (room) light. Most reading conditions are in

relatively low room lighting and the default of 0.0 cd/m2 should be used. For rooms with

bright lighting such as Operating Rooms, values of 1.5 to 2.0cd/m2 are common.

Calibration Steps The default of “0,5,10,15…” should be selected. This takes 52 measurements. Selecting

smaller steps (more measurements) may slightly improve the calibration but will take much

longer to complete. Selecting larger steps (0,15,30,45…) and below is not recommended

except for certain testing purposes.

Verification Steps The default of “0,15,30,45…” should be selected. This takes 18 measurements. Selecting

smaller steps (more measurements) may slightly improve the verification but will take much

longer to complete. Selecting larger steps (0,17,34,51…) and below is not recommended

except for certain testing purposes.

CFS Scheduler Tab

Back Light Intensity settings

All Image Systems displays utilize an internal backlight sensor to measure the brightness of

the backlights every minute. By adjusting the “Auto-adjust when off target by” setting you

can control how closely the displays will maintain the Target White level luminance value set

on the General tab. Settings of 3% to 5% are typical. Should the luminance value vary more

than the “Log alert when off target by” setting, an alert message will be logged in the Event

Log. Typical settings are from 5% to 7%. The “Check brightness value every” should be set

to “sliding scale” when an AFS (Add on Front Sensor) is used. This allows CFS to act as a

Stable Backlight Control (SBC) for displays lacking this built-in feature.

White Level Luminance This section sets the schedule on which a White Level Luminance check will occur

automatically using the Side Bezel Sensor built into each display or the AFS option. The

default setting is once per month on Friday at 8pm. Typically this check is scheduled during

off-hours so as to not disrupt workflow. Common frequency settings are once per week or

once per month. During the scheduled check, should the reading vary outside of the Auto

adjust target (typically 3%) CFS will automatically change the White level to the Target White

level luminance value set on the General tab and log an alert to the Event Log if the reading

varied outside of the Log alert target (typically 10%).

DICOM Compliance This section sets the schedule on which a DICOM verification check will occur. Typically this

check is scheduled during off-hours so as to not disrupt workflow. The default setting is once

per month on Friday at 8pm. Common frequency settings are once per week or once per

month. During the scheduled check, should the reading vary outside of the Auto adjust target

(typically 5%) CFS will automatically recalibrate and log an alert to the Event Log if the

reading varied outside of the Log alert target (typically 10%).

Auto Generate Report The “Auto-generate reports file” drop list is used to select which calibration report will be

created each time a compliance check is run (see a sample DICOM report on page 31). The

report file is saved in C:/Image Systems/Reports. The default file name is the local computer

name with the current date appended to the end. The file type is HTML. The “File name” field

in the “Event Log Export” section on the Preference tab sets the file name used for export of

the CFS log file and the CFS Calibration Report. Reports can be accessed from the Reports tab

by double clicking a report in the Archived Reports list.

NOTE: If your displays are in the Windows power saver mode when a scheduled White Level

Luminance or DICOM Compliance check occurs CFS will automatically power up the displays,

wait 15 minutes for the displays to warm up and then initiate the check.

Visual Acceptance Scheduler This section configures CFS to display a confirmation image along with an informational

message on a scheduled basis. The visual confirmation notice will remain on the screen until

the user enters their name or initials (at least 3 characters). The user can opt to delay the

test for 5 minutes. The test image(s) will be displayed on each diagnostic display and the user

must accept or reject each one. If an image is rejected, the user may enter a reason. See the

preference tab to configure the informational message and select a confirmation image.


Example Visual Acceptance image with default message.

Front Ambient Sensor Control All Image Systems Professional-Series displays have a front ambient room lighting sensor. CFS

receives current room lighting readings from this sensor and alerts the user should the

lighting change significantly from the reading taken during the last calibration process. Should

the reading vary greater than the “Display warning when brighter by” setting a pop-up

warning will appear. The “Check ambient LUX every” setting adjust the time interval for CFS

to take readings from the Front Ambient Sensor (LUX - a measure of the apparent intensity of

light). In the case of a pop-up warning it is recommended the user either returns the room

lighting to the conditions set at the last calibration or recalibrates the displays.

NOTE: With Image Systems M-series displays this section does not apply.


CFS Event Log Tab

Event Log The Event Log tab shows all past CFS activity. The information is stored in a text file on the

C: drive of the local computer. While in CFS administrator mode the log file can be edited or

exported to any location on the local computer. Settings in the Preference tab allow for

automatic export of the event log on a user-defined schedule as well.

Clicking on a Heading will

sort the Event Log by the

selected item.

The default is sort by Date and Time


CFS Preferences Tab

Permission Popup When a scheduled event from the Scheduler tab is initiated a popup message will appear on

the screen. The popup box allows anyone sitting at the system to initiate or terminate the

scheduled event. If no action is taken the event will execute automatically after the set

countdown time. Should a user terminate a scheduled event a message is recorded in the

event log and an error message is sent to the CFS WebManager.

The default file name is the local computer name. Selecting the Append date to file name box

will append the date to the end of the file name. Purge log file after export is recommended

to keep the Event Log file at a manageable size. (The Event Log will automatically truncate

old entries after reaching 2048 lines) Exporting the Event log on a monthly basis is common.

Visual Acceptance When the Visual Acceptance Image is set or enabled on the Scheduler tab a default SMPTE

image and generic message are displayed. To select a different image enter the path and file

name in the Confirmation Image box. Click the “Browse for image” box to browse. GIF,

Bitmap and DICOM formats are supported. To change the default message, type your desired

message in the Confirmation message box.

CFS Activation Code Some display and video card combinations require an activation code for CFS to continue

functioning after the 30 day trial period. After 30 days the popup message below will appear

when the CFS service starts. Contact Richardson Electronics Healthcare technical support to

receive a valid activation code.

Auto Update Function This option allows CFS to update to a new minor version of CFS automatically i.e. L5 to L6,

but not L6 to N1 (major version number change). The latest CFS version can be found at

http://www.rellhealthcare.com/downloads . Update one system to the new version. Copy the

ISCcfs.exe file found in C:/Image Systems/CFS folder to the path specified in the “UNC Path”

setting on all other systems running CFS. At the next computer reboot CFS will check the

“UNC Path” location for a new version and update automatically.

NOTE: Path names must follow the Windows Uniform Naming Convention (UNC). UNC names

identify network resources using a specific notation. UNC names consist of three parts - a

server name, a share name, and an optional file path. These three elements are combined

using backslashes as follows: \\server\share\file_path.

Cursor Behavior Cursor Genie prevents the mouse cursor from getting trapped in the corners in a multi

monitor setup where the top and/or bottom of the displays don’t line up exactly. Cursor Wrap

allows the mouse to jump from the far left edge to the far right edge and vice-versa. It is also

possible to set a hotkey to determine where the cursor is currently sitting.

PinPoint Behavior PinPoint isolates a region of interest by dimming all screens leaving a high contrast window

centered on the mouse pointer. The PinPoint Size field sets the initial size of the window, but

it can be adjusted by clicking the scroll wheel or the left mouse button while rolling the scroll

wheel, or with the right/left arrow keys. The PinPoint Hotkey drop list sets the key

combination that opens the PinPoint window. It can also be opened by right-clicking on the

CFS icon in the system tray and selecting “PinPoint”. The image in this area can be magnified

using the scroll wheel or the up/down arrow keys. Click the right mouse button or press the

Esc key to return to normal mode.

PnP Table The PnP (Plug and Play) Table allows users to customize how non-Image Systems displays

attached to the computer are recognized by CFS and added to the CFS calibration process.

For example, by adding the Plug and Play number for a NEC 2190 to the PnP Table, CFS will

add a display tab for this display and allow calibration with either an optional AFS or the hand

held Image Systems USB photometer. Only displays that support DDC communication and

VESA standards for brightness control are supported. The user can also use this mechanism

to instruct CFS to ignore recognized displays. Open the CFS dialog box and click on the

Preference tab. Select the PnP Table button at the bottom of the window. Click inside the

popup PnP table window and add the PnP number of a supported display. Now select the

appropriate communication protocol for the display. After reboot CFS will add a Display tab

for the display. Contact your Richardson Electronics Healthcare support team for help

establishing the PnP number for your display.

Example PnP Table


App Table The Application Table is where users can set up a Gamma Mode and Brightness for an

individual application or multiple applications. For example if the user looks at PACS images

on a high bright diagnostic monitor and opens Microsoft Word documents on a regular basis

they may experience eye strain due to the bright white MS Word page. The user can open MS

Word, open CFS to the Preferences tab, select the App Table button, choose MS Word from

the active Application pull down menu, choose a gamma mode of 0.0, a brightness of 50%,

and click the Add New Application button. After clicking confirm to exit the App Table, when

the user opens an MS word document, the monitors’ brightness will be automatically reduced

by 50% and the gamma table will be changed from DICOM to 0.0 (no gamma) allowing the

user to experience less eye strain. If the user opens up the PACS software to look at medical

images, CFS will automatically adjust the brightness back to the Target White Level and the

DICOM calibrated gamma table set up as shown on page 18.

Available Gamma Modes

0.0 – No gamma correction.

+2.2 – Optimized for typical display use.

-4.0 – Optimized for gamma 4.0

DICOM – Optimized for DICOM GSDF.

CT/MRI – Optimized for CT/MRI images.

Ultrasound – Optimized for Ultrasound images.

Device Parameters The Device Parameters section displays information read from the attached displays internal

memory. Also displayed is the current driver for the displays graphic card and last date and

time of calibration of the Front Bezel Sensor along with the serial # for the Image Systems

calibration puck used to last calibrate the front sensor. Calibration of the front sensor can be

initiated by clicking on the “immediate action” box.

*To ensure accurate calibration we recommend the front sensor be recalibrated to

the Image Systems hand held USB photometer on a yearly basis.

Front Luminance Sensor selection This should be set to “Integrated” to utilize the retractable front sensor built in to each

display. The “USB Puck” (hand held puck) setting is used to facilitate calibration of supported

displays that do not have a Side bezel Sensor.

Color Point Adjustment The Color Point Adjustment section allows for color point matching of color displays.

To match a color point value, select a Color Point Target on the General Tab. Checking the

“Capture XY Color Point” box will facilitate capture of the color coordinates of the display. The

XY coordinates and color temperature are displayed on the General Tab. Additional displays

can now be color adjusted to these coordinates by checking the “Color Point Calibration” box

on the respective Display tab.

Lamp Parameters The Lamp Parameters section displays information on the state of the backlights. As the

backlights age, the Lamp Power Level value will slowly increase.

Luminance Parameters This section displays the target White Level for the display associated with the current Display

tab. Changing the target value will affect only the display associated with the current Display

tab. To initiate an immediate White Level check, click the corresponding immediate action

box. This will activate the front sensor and check the white level. To adjust the white level,

click the second immediate action box.

DICOM Parameters The DICOM Parameters section displays important information about the current DICOM

calibration parameters. The last date of DICOM calibration and verification along with the

percentage deviation from nominal are shown. Checking the “Check for DICOM Compliance”

immediate action box will activate the front sensor and start a DICOM check for compliance.

To run a complete DICOM calibration process check the “Recalibrate to DICOM Standard”

immediate action box.


Rollback to previous DICOM Curves Each time DICOM calibration is performed, CFS saves the previous calibration file(s). The user

can choose to “rollback” to previous DICOM calibrations.

Clicking on the Rollback [immediate action] box opens a list of past calibration files for the

corresponding display. Example: “Dicom 120220” represents calibration file created on Feb.

20th of 2012 for the first display (Display 1).

Click on box to open list of

previous DICOM calibration files.

Select file to “Rollback” to previous calibration.


“LOG” and “LIN” Graphs Graphs for each display are found on the Display tab.

Graph 1 “LOG” Graph 2 “LIN”

Graph 1 “LOG”

Shows the target versus actual luminance at each digital driving level as the mouse is moved

across the graph from left to right. The ideal graph will show a straight diagonal line between

the black and gray areas.

Graph 2 “LIN”

Shows the target versus actual JND (Just Noticeable Deference) step at each digital driving

level as the mouse is moved across the graph from left to right. The ideal graph will show

only small deviations (less than 4%) above and below the base line.


“LUM” and “FIT” Graphs Graphs for each display are found on the Display tab.

Graph 3 “LUM” Graph 4 “FIT”

Graph 3 “LUM”

Troubleshooting and Support

Front Sensor stuck in the ‘in’ or ‘out’ position On rare occasions such as a power failure or mechanical problems the retractable front sensor

could get stuck in the ‘in’ or the ‘out’ position. Should this happen, DO NOT manually force

the sensor by prying it out or forcing it back in. Open the CFS dialog box and select the

Display tab for the display with the stuck sensor. Select the “Check White Level Luminance”

[immediate action] box to deploy the sensor. For sensors stuck in the out position, follow the

same procedure and then click “Abort”. The front sensor should retract. If the sensor does not

deploy or retract please contact your service representative.

Event Log shows DICOM or Luminance Maintenance bypassed Probable cause is the Bezel (Front Sensor) is not calibrated or DICOM calibration was not run

at initial install (see install instructions to calibrate front bezel sensor or run DICOM

calibration).

Calibration puck driver problem (“The Specified Sensor is not responding”) On rare occasions the driver for the hand held calibration puck can become corrupt.

Sometimes simply plugging the puck into another USB port will remedy the problem. A

system reboot may also work. If problem still persists, the driver may need to be reinstalled.

Open the “Unplug or Eject hardware” icon from the tool tray. Click on properties and then the

driver tab. Click on uninstall and then close. Unplug the puck from the USB port and then

reinsert into same USB port. The Found New Hardware Wizard will start. Click Next / Select

“Search for a suitable driver…..” (Default) Click Next. Select “Specify a location” only. Click

Next. Browse to C:\Image Systems\Support Files\ Click Ok / Next / and Finish.

Pop-up window with 30 day warning appears at boot up

CFS activation code not entered or entered incorrectly. See the Preferences tab section for

instructions on entering the CFS activation code.

CFS Display tab missing (two displays connected but only one tab present) Un-checking the display with no tab, and re-checking should resolve this. Alternately, unplug

power to the display not being recognized, reconnect, and reboot the computer. If this does

not correct the situation the graphic card drivers may not be installed correctly. Contact your

service representative for help installing the graphic card drivers.
