8. NORMAL MODE OF OPERATION

8.1. OPERATING PREPARATION A. Wear a lead apron while you make exposures. B. Stay distance at least 2 m from the unit or extend the cord of hand switch as long as possible in

order to secure enough space for your safety. C. Use proper field size and technical values for each procedure to minimize x-ray exposure dose

and gain the best radiographic result. D. Be careful about the decimal point on the mAs display in order to acquire intended mAs values. E. When you make exposure to the patient on the bed, ask visitors to leave the room first and

keep appropriate distance from the patient. F. Pay attention to the maintenance schedule of the device and keep up with it. G. Cumulative radiation dose usually does not exceed recommended maximum levels. However, if

you make radiographic exposures using high kV and mAs quite often, the evaluation of the specialist is needed to check whether extra protective devices are necessary for the user or not.

8.2. COLLIMATOR AND LASER POINTER CHECK A. Place the loaded cassette on the patient’s backside. B. Arrange the SID (Focal Spot to Image Receptor Distance) using a scale located on the side of

the collimator. C. Turn on the collimator lamp and laser pointer by pushing collimator/laser on switch. D. Adjust the size of the x-ray beam in accordance with the film size using the x-ray field

adjustment knobs. Turn off the collimator and laser pointer after 30 seconds on the timer.

WARNING Please check the input voltage and the power requirement are in accordance with the system labels, which attached on the body of the machine. The input voltage tolerance within + 10% is acceptable for normal operation.

CAUTION Verify thoroughly a power cable and other cable interconnection before operating the portable and making x-ray exposure.

CAUTION When the portable is first used after purchase or x-ray tube is cool, x-ray tube is needed for warming up to secure long life of the tube. Following method of pilot test will relieve the damage on the x-ray tube. Operate the machine with low kV values (50kV, 5mAs) three times consequently and execute with higher values [90kV, 50mAs].

9. REMOTE CONTROL FUCTION & OPERATION 9.1. INTRODUCTION Currently, mAs, kVp and Pre-set memory techniques (PROM memory) can be selected by the operator by depressing push buttons or by scrolling displays on a control panel. Each technique or mode selection depends on an anatomic region or view for radiographic examination. The collimator lamp and laser pointer is turned “on” by the lamp push-button and turned “off” by a 30 second collimator timer run off. Many portable operators and field users have suggested we find a better way to select an exposure technique and parameters along with mAs, kVp and pre-set PROM memory values. Most field operators hold portable X-Ray units with one hand, while holding the exposure hand switch with the other hand. This makes selecting technique factors on the control panel awkward without dropping the portable unit or hand switch. We have modified our X-ray portable software and functions of the Prep. and Exposure hand switch to allow selection of all exposure parameters (mAs & kVp) and control of the collimator lamp and laser beam. The exposure hand switch consists of a two step hand switch. The first (1) stage of the hand switch is called the “Preparation (Prep. or Ready)” stage. The second (2) stage of the hand switch is called the “Exposure (Exp or X-Ray out)“ stage. (See drawing 1.) All functions of the remote control described above are executed by clicking the first stage on the hand switch which is the “Prep.” mode of operation. Each remote control function and technique value selection is described below. (Drawing 1) 9.2. REMOTE CONTROL MODE

The kVp and mAs setting, memory selection and collimator lamp and laser pointer illumination functions are controlled remotely by the hand switch by pressing the “Prep.” stage push-button as follows:

<TRIPLE CLICK>

9.3. MEMORY SELELCTION When you click the PREP stage hand switch quickly three (3) times, the Pre-set Memory station LED (PXP-60HF: 1-8) will blink sequentially as well as the kVp and mAs LED readouts. Make a single (1) click with the hand switch when the desired pre-set memory station lamp begins to blink. This will cause the pre-set memory data to be selected and displayed in the control LCD window.

9.4. kVp SELELCTION One (1) click of the “Prep” switch will cause the kVp LED readout to blink. You will now be in the kVp selection menu mode. The kVp values increase by one (1) kVp unit per click of the “Prep.” switch. If you depress and hold the prep switch for a few second, the kVp readout will increases rapidly up to the maximum value (PXP-60HF: 100 kVp). The kVp readout will circulate from lowest to highest values as long as you hold and press the button. When the desired kV readout appears on the control

ATTENTION Click the “Prep.” hand switch three (3) times consecutively. This will allow you to enter in the “remote hand control” menu mode for operation.

NOTE All pre-set memory data should be entered and stored at each memory station (PXP-60HF: 1-8), prior to performing the above mode of operation.


17

display panel, release the prep hand switch and wait for a few seconds. The kVp value will set up automatically.

9.5. mAs SELECTION mAs selection is similar to the kVp selection mode. Click the “Prep” hand switch once to make the mAs LED readout blink. You will be in the mAs selection menu mode. The mAs value will increase with each click of the “Prep” switch (0.4 mAs to the maximum mAs of each portable x-ray unit). If you wish to increase the mAs value quickly, simply hold the “Prep” switch down one stage. (PXP-60HF: 100 mAs). The mAs readout will circulate as long as you hold the “Prep” switch. When the desired mAs readout appears on the control display panel, release the prep hand switch and wait for a few seconds. Then mAs value will set automatically. 9.6. COLLIMATOR / LASER BEAM TURNED ON <DOUBLE CLICK> With the exposure technique (mAs & kVp) set with your remote hand switch, you are ready to make a radiographic exposure for examination. It is very important to position the right region of interest on a patient’s anatomy. Therefore, the collimator beam must be turned on to confirm the size of region and size of film covered. The laser beam must also be turned on for checking the precise center of the target prior to making a final X-ray exposure. When the Prep switch is rapidly clicked twice, the collimator lamp and laser beam will turn on simultaneously until the lamp timer (30 seconds) runs off. However, it will turn off automatically when x-ray exposure sequence is completed. 9.7. X-RAY EXPOSURE After the x-ray exposure technique is selected and collimator light beam size is adjusted with the collimator blade knob, an x-ray exposure can be made by an authorized individual of the medical clinic or hospital.

ATTENTION Click the Prep. hand switch rapidly twice. The collimator lamp and laser pointer beam will illuminate for X-ray exposure positioning.

WARNING When an X-ray exposure is made in a room or outdoors, lower radiation will scatter throughout the surrounding area. An authorized operator is expected to take precautions and is highly recommended to ware a lead apron and gloves if necessary for your patient’s and your own protection.

X-RAY EXPOSURE SEQUENCE: A. Press the Prep hand switch (1st stage) and hold B. Press down the 2nd stage hand switch. Exposure will be made automatically by the exposure timer.

< 1ST STAGE> <2ND STAGE> 9.8. REMOTE CONTROL OVERRIDE

NOTE TO THE USER All of the before mentioned remote control hand switch functions and operations can also be accomplished via the one-touch control panel. All exposure functions and parameters can be Overridden through the main control panel prior to final exposure. (See user’s manual for directions on how to use the main control panel)

-PREPARATION

Following tools and instruments are needed. a. Tools: Philips screwdriver No.1 & 2, Straight slot screwdriver b. Instruments: DVM, oscilloscope (Tektronics TDS 3032 and more than Equivalent)

4. CALIBRATION PROCESS

4.1. Line Power Supply

-Line switch should be at off position. -Connect power line cord to the power outlet. -Turn on the line switch. -Then the LED on the operation panel illuminates.

4.2. Calibration procedures are composed of three steps. -Tube voltage confirmation and calibration. -Tube current confirmation and calibration. -Filament preheat calibration

A. Calibration and Confirmation of Tube Voltage -Turn off the line switch. -Lift up the control panel from the unit, and then the PCB OP board appears. -All DIP switches on the PCB OP board are turned off. (Note: DIP switch is usually located in this location.)

-Connect the channel one probe of the oscilloscope to TP5 (IP F/B). -Connect the channel another one probe of the oscilloscope to TP6 (EP F/B).

-Connect the ground to TP11 (GND). -Turn on the line switch and the display indicates as follows.

-Set the kV and the mAs at 40kV and 0.4mAs (60mA). Then observe the mA waveform of the oscilloscope channel 1.

-If it is not about 9V, adjust mA by VR3 on the OP board. Then observe the kV waveform of the oscilloscope channel 2.

-If it is not 2V, adjust kV by VR2 on the OP board. After adjustment, set the tube voltage kV to 80KV by the kV up/down switch.

-Set the kV and the mAs at 80kV and 0.4mAs(40mA).Then observe the mAs, kV waveform of the oscilloscope channel 1, 2.

Channel 1 is mA, and 60mA = 9 V Channel 2 is kV, and 40kV = 2V

-If it is not about 6V, adjust mA by VR3 on the OP board. -If it is not about 4V, adjust kV by VR2 on the OP board.

B. Calibration and Confirmation of Tube Current

-Turn off the line switch. -Lift up the control panel from the unit, and then the PCB OP board appears. -All DIP switches on the PCB OP board are turned off. (Note: DIP switch is usually in this position.) -Connect the channel one probe of the oscilloscope to TP5 (IP F/B). -Connect the channel another one probe of the oscilloscope to TP6 (EP F/B).

-Connect the ground to TP11 (GND). -Turn on the line switch and the display indicates as follows.

-Set the kV and the mAs at 40kV and 0.4mAs (60mA). Then observe the mA waveform of the oscilloscope channel 1. -If it is not 7V, adjust mA by the calibration data on the OP board. -Turn off the line switch, and wait until the display switch the light off. -DIP switch 1 on the PCB OP board is turned on. -Turn on the line switch and the display indicates as follows. -Then push the mAs up switch (see operation sheet). The display indicates as follows.

C00 is calibration code of tube current (60mA at 40kV~50kV). 179 is calibration data of tube current (60mA at 40kV~50kV). -Adjust mA by the mAs up/down switch (see operation sheet). -After it is adjusted, push the store switch (see operation sheet). -DIP switch 1 on the PCB OP board is turned off then exposure X-ray. -If it is not 9V, set the calibration data again. -DIP switch 1 on the PCB OP board is turned on. -Then push the kV up switch (see operation sheet).

Channel 1 is mA, and 60 mA = 9V Channel 2 is kV, and 40 kV = 2V

The display indicates as follows.

C01 is calibration code of tube current (40mA at 51kV~70kV). 153 is calibration data of tube current (40mA at 51kV~70kV). -Adjust mA by the mAs up/down switch (see operation sheet). -After it is adjusted, push the store switch (see operation sheet). -DIP switch 1 on the PCB OP board is turned off then exposure X-ray. -If it is not 6V, set the calibration data again. -Table .1 shows the calibration code and the calibration data against an each tube current.

C. Filament preheat calibration

-This is preheating filament for making tube current. -The overshoot or the undershoot may occur from the tube current if the preheat calibration data or the VR3(preheat gain volume) is set by mistake.

-There are two methods to make preheat calibration setting. The calibration data is possible to be changed in accordance with the tube condition.

-The VR3(preheat gain volume) adjusts the whole range of tube current. Filament preheat calibration data adjusts each tube current.

-Turn off the line switch. -Lift up the control panel from the unit, and then the PCB OP Board appears. -DIP switch 1 on the PCB OP board is turned on. -Turn on the line switch.

-Push APR switch ① and then the display indicates as follows.
