Safety

Safety NOTE:

Safety glasses and safety shoes are required when performing any installation, servicing or maintenance of equipment. See the hazard matrix in the following Energized Electrical Work Procedure for specific PPE relative to energized electrical work.

Energized Electrical Work Procedure Note:

All electrical circuits or energized parts shall be de-energized and rendered safe using the appropriate Lockout/Tagout (LOTO) procedure, unless energized system testing, positioning, or adjustment is required. When energized work is required, this procedure must be used – inconvenience is never acceptable.

Definitions NFPA 70E – is a national consensus standard that forms a “Standard for Electrical Safety in the Workplace.” It is also a part of the National Electrical Code, which has been adopted by OSHA as an enforcement standard. Arc-flash – an explosion of electrical energy that can cause burns and other injuries. An arc-flash is essentially a short circuit through the air. Qualified Individual – an authorized employee who has been properly trained and certified (verified) to work on energized equipment. Anyone not meeting these requirements is an un-authorized individual.

Purpose To mitigate the electrical safety hazards (arc-flash) associated with energized system testing, positioning, or adjustment (calibration) of GEHC/OEC equipment - in accordance with the NFPA 70E consensus standard.

Training Requirements It is the obligation of each GE Field Service Engineer to follow this procedure and understand that failing to do so can cause serious injury or death. Only Field Service Engineers who have completed: • LOTO Authorized [LOTOAth] • Electrical Safety Authorized [GE-EHS-280-a] and • Hands-On Demo [CEP-38] … … training will be considered a “Qualified” employee and permitted to work on energized GEHC/OEC equipment. All other non-authorized personnel will be considered “Affected” individuals.

Safety

In addition, “Qualified” Personnel must be trained on the proper use of voltage testing equipment. The training must include: •

How to apply the test instrument to the circuit or energized part

•

How to interpret meter readings

•

How to test to confirm the absence of voltage.

•

The need to test equipment prior to and after use.

Special Precautions Conductive articles of jewelry shall be removed from the hands, wrists, and shirt pockets. Tools and test equipment shall be visually inspected prior to use. Individuals shall be aware of their surroundings and take precautions to prevent accidental contact with the energized electrical circuits. Each “Qualified” person is responsible for ensuring that non-authorized individuals remain outside the “Default Approach Boundary.” When ever possible, protective barriers should be erected around the flash protection boundary as means to protect “Unqualified” personnel from the effects of an arc blast. Insulated tools used within the restricted boundary must be rated for the nominal voltage of the system being worked on. Only ladders possessing non-conductive side rails (e.g. fiber glass) shall be allowed within the “Limited Approach Boundary.”

Emergency Procedures: In case of an accident 1) De-energize the system. 2) Immediately call 911 or summon hospital staff. 3) Check the victim for injuries. 4) Care for victim until help arrives. 5) Report incident to manager and/or EHS staff.

Application of Energized Work Procedure: 1) Plan for energized work. 2) Locate energized work procedures. 3) Notify customer of energized work and associated hazards. 4) Inspect and apply proper PPE for hazard class (see Hazard class section). 5) Determine arc-flash boundaries (see Hazard class section).

Electrical Hazards and Hazard Classes: Hazard: Accidental contact with exposed energized circuits resulting in electrical shock or arc-flash.

Safety

Lock-Out, Tag-Out This procedure meets the basic LOTO requirements established by OSHA and follows the policy of GE Healthcare for energy-isolation during the service/maintenance of this equipment. It is designed to insure that each employee involved in servicing this equipment has exclusive control over when the equipment is reenergized (i.e. each employee maintains a personal lock with a unique key). It is the obligation of each employee to follow this procedure and understand that failing to do so can cause serious injury or death. Only Field Service Engineers who have complete LOTO Authorized and initial LOTO Verification training will be permitted to execute Lockout/Tagout on this system. All other non-authorized individuals will be considered “affected” individuals.

When servicing the Workstation alone, the system is considered a single energy source if and only if the C-Arm is disconnected (by removing the Main Interconnect Cable) and the power cord is under the exclusive control of the authorized employee performing service. As long as the authorized employee can retain exclusive control over the power cord, the 120 VAC electrical energy source can be considered controlled and service can proceed. If at any time service involves maintenance of the C-Arm, the following “Energy Control Procedures” are mandatory and must be implemented by authorized Employees.

Energy Control Procedures 1. Notify all affected individuals of a shutdown. 2. Verify safety of work area. 3. Identify all electrical sources. 4. Position C-Arm for service. 5. Shut down system via green main power switch. 6. Remove A/C plug from wall power.

9

Safety

7. Remove interconnect cable from C-Arm. 8. Apply the red lock and tag to the AC plug as shown in the figure below.

9. Remove workstation rear and side panels. Disconnect J10 from the ISD board. (This isolates AC power coming from the UPS). 10. In the workstation verify zero volts AC at TB1 between the brown and blue wires. 11. On the C-Arm turn off battery circuit breaker CB1 located under the front right side below the power cap module.

10

Safety

12. Remove C-Arm covers.

Safety

13. At the top of the power cap module disconnect red and black battery connectors. Verify zero volts DC across previously removed red and black battery connectors. 14. Power is now locked out. NOTE:

In the event service will continue into another day, and/or the machine will cause a hazard if reenergized after the authorized employee leaves the location, leave the A/C cord cover installed with a “transition” lock and yellow tag attached. If more than one authorized employee is going to conduct service on the same system, at the same time, multiple locking devices must be employed and each authorized employee must adhere to the entire LOTO procedure.

Testing and Positioning During Service In the event that lockout/tagout devices must be temporarily removed from the energy isolating devices, for testing or positioning purposes, the following sequence shall be followed:

1. Clear the machine of tools and materials. 2. Ensure that all employees/individuals in area are safely positioned or removed. 12

Safety

3. Remove energy control measures. 4. Energize system and proceed with testing or positioning. 5. De-energize system and reapply energy control measures.

Restore Power After Service 1. Re-inspect work area for hazards. 2. Reconnect red and black battery connectors to the power cap module 3. Reinstall C-Arm covers. 4. Turn on CB1 on the C-Arm. 5. Install workstation covers. 6. Connect main interconnect cable to the C-Arm. 7. Notify all affected personnel that power is being restored. 8. Remove red lock and tag 9. Energize the system. 10. Verify proper system operation. 11. Inform customer that system is ready to be returned to service.

WARNING:

High voltage cables, electrolytic capacitors, and CRTs can retain a dangerous static charge for long periods after power has been removed. Some devices can acquire a charge spontaneously without direct contact with other circuitry. Do not touch these components unless power has been completely removed and they have been discharged. Equipment that contains high power electrical components must be serviced only by personnel familiar with proper safety procedures for working near these components. Disconnect AC power (and battery packs if used) before discharging static electricity in components such as electrolytic capacitors and high voltage cables. Failure to heed this message will result in death or severe personal injury. Allow adequate time for static charges to discharge through bleeder resistors. Use a high wattage resistor when discharging circuits to avoid burns. Have someone watch while you work near high voltages. This person must remain clear of all circuitry and be prepared to turn off the power to the system and render aid in an emergency.

WARNING:

Systems with battery packs can deliver high currents at high voltage. Electric shock from batteries can cause death or personal injury, including severe burns. Use extreme caution when working on circuits energized by or located near the batteries. Batteries are dangerous at all times. Setting the battery pack circuit breaker to off removes battery current from other circuitry, but does not render the batteries harmless.

13

Safety

CAUTION:

Never operate the system unless all potential equalization conductors (green wire with a yellow stripe) and related components are fastened in place. Dangerous electrical shock and improper equipment operation can result.

CAUTION:

Remove all metal rings and watchbands before working on system circuitry. Skin burns and damage from involuntary muscle contractions can result if metal jewelry shorts electrical circuits.

Power Distribution and Control

Power Distribution and Control Intelligent Shutdown Power Control PCB (ISD-PC2 PCB) The Intelligent Shutdown (ISD2) Power Control PCB prevents the system from powering up if the AC line power is faulty or if applying AC power to the system would create a condition that is dangerous to the operator or the equipment. For example, if the Lemo connector is disconnected from the C-arm Lemo jack, it is not possible to power up the C-arm because AC power in the Interconnect cable is disabled to prevent electric shock. Through the uninterruptible power supply (UPS), the ISD Power Control PCB can also prevent premature shutdown of the system and data loss during a power failure or accidental shutdown. The ISD protects the Workstation in the following ways: • Controls the application of AC power to the Workstation electronics and accessory outlet strip. • Controls the application of AC power through the Interconnect cable to the C-arm. • Prevents the application of AC power to the C-arm when the Lemo connector is unplugged from the C-arm. • Senses AC mains applied voltage at power-up. Inhibits power-up if line voltage is out of range and sounds an on-board alarm to alert the operator or field service engineer. Operates LEDs that display power condition. Green LED DS1 glows when AC line voltage is OK. Amber LED DS2 glows when line voltage is too low. Red LED DS3 glows when line voltage is too high. • If you press the Workstation power switch to turn it off, and main AC power is still available to the Workstation, the system will not shut down until system software determines that all data-preservation steps are complete and it is OK to shut down. • Under software control, K9 on the ISD2 selects either unprotected AC from the AC line or battery-protected AC from the UPS to power the Workstation. • Provides status information to the Workstation software through the System Interface PCB and receives power-control commands over the same path. • Causes Workstation power switch to flash when you turn the Workstation off. The flashing continues until shutdown is complete, at which point the switch lamp turns off. • Interfaces with the UPS Off switch, which operates relay K9 to disconnect the UPS output from the Workstation. • Generates the UPS Off signal through K10 to turn the UPS AC output off.

16

Power Distribution and Control

Uninterruptible Power Supply Workstations have a 230 VAC-operated uninterruptible power supply (UPS), which generates modified sine wave 230 VAC from an internal battery-powered inverter if the AC line fails. This enables orderly system shutdown during a power failure so that no important patient data or images are lost. The UPS also protects the Workstation from power sags, power surges, brownouts, and line noise. Other important features of the UPS include the following: • Battery-management software that effectively doubles the battery service life. The software optimizes battery charging and provides advance warning of impending battery failure. • Buck and boost voltage regulation that corrects AC line voltage fluctuations. • Start-on-battery capability that allows you to turn on the UPS even if the AC line power is not available. • Accepts control signals from external equipment. The Workstation UPS mounts inside the Workstation just above the transformer pan and has a capacity of 1400 VA. It appears as follows:

Power Distribution and Control

Front-Panel Controls and Indicators The UPS front-panel controls and indicators shown below are accessible behind the right Workstation cover (viewed from the front of the Workstation). The UPS external circuitry appears on sheets 4 and 5 of Interconnect Diagram 885899. When the Workstation is on, the ISD-PCB supplies a low on P12-2- to pin 3 of the UPS communication port, turning the UPS on. When the UPS is on, it supplies AC power to its rear-panel receptacles by switching AC power from its input connector. The AC power at the input connector comes from the ISD PCB. After the UPS is on it conducts a self-test, and if all is well it enters Normal mode. The green Power On indicator glows, indicating that power is available from the UPS rear-panel receptacles. If the AC mains power fails, the UPS supplies power to the system using its internal battery and inverter. The green Power On indicator goes out and the yellow On Battery indicator comes on. An audible alarm sounds. The UPS receives AC power whenever the system power switch is on. The battery recharges if necessary. Refer to the UPS Fault Indicators table at the end of this section for more information on how the UPS front-panel controls and indicators behave in various error conditions.

Power Distribution and Control

Input Connector Supplies 230 VAC to the UPS.

Cooling Fan The UPS fan and Workstation cooling fans must operate at all times the system is on, or the Workstation will overheat.

UPS OFF Switch The Workstation has a UPS OFF switch, which enables you to turn the system off manually even if the UPS is currently powering it. CAUTION:

This switch turns the system off immediately without the protection of software controlled shutdown. Because there is risk of data loss or corruption, use this switch to turn off the system only when absolutely necessary.

The UPS OFF switch is located on the rear panel of the Workstation. There is a clear plastic protective panel over the switch, that you must lift before operating the switch. If AC line power is available, an LED behind the switch lights when you press the switch. If the Workstation is being powered by UPS battery power, the LED lights and the ISD -PC2 alarm sounds until power is removed. The LED and alarm serve as reminders if the UPS Off switch is still engaged when AC power returns.

21

Power Distribution and Control

UPS Off Switch Refer to sheets 4 and 5 of Interconnect Diagram 885899 and to sheet 3 of ISD PC2 Schematic 887456 when reading the following description of the UPS Off switch. After the system boots completely, the system routes AC line power through the UPS to the Workstation. This permits a rapid switchover from AC line power to UPS power in the event of a power failure. K9 energizes after bootup and remains energized if AC power fails. CAUTION:

When the system operates on UPS battery power it may become necessary to shut the system down immediately to prevent equipment damage, even though some loss of data may occur.

Press the normally closed UPS Off switch on the back of the Workstation to accomplish this. Pressing the UPS switch causes P11-5 to go high. This turns on transistor Q10, pulling the UPS_SEL line (U8-7) low and de-energizing relay K9. This shuts off power from the UPS. When P11-5 goes high, it also lights the UPS Off lamp if battery power from the UPS is still available.

22

Power Distribution and Control

UPS Functional Tests Uninterruptible Power Supply Self-Test

CAUTION:

Removing the Workstation's covers in the following step exposes high-voltage points within the Workstation. Avoid contact with these points as you perform the following procedure.

1.

Remove the front, side, and rear Workstation covers as described in the Replacement section of this manual.

2.

With the workstation plugged in and not powered up, press and hold the Test/Alarm Reset button for three seconds to initiate a self test. The UPS automatically distributes the load to the batteries for 15 seconds and tests the battery’s performance. If there is a problem with the battery, the On Battery indicator glows and the Service indicator flashes. Check the battery connections and be sure that the battery is fully charged.

Uninterruptible Power Supply Battery Test The UPS inside the Workstation can power the Workstation for a limited amount of time when the system loses AC power. This allows the operator to shut down system operation in an orderly way to avoid the loss of patient images and data. The UPS uses an internal sealed lead acid (SLA) battery as the primary source of power during power outage emergencies. The SLA battery powers an inverter inside the UPS, which generates AC power for the Workstation. Note:

The C-arm shuts down immediately when the Workstation loses AC power. It is not possible to generate X-rays during a power outage.

The AC line supplies charging power to the UPS internal battery charger as long as the Workstation's AC line plug connects to an active AC outlet. Circuitry inside the UPS turns the charger on and off as necessary to keep the UPS SLA battery charged. The following procedure tests the UPS battery only. It does not test any other circuitry inside the UPS or elsewhere. 1.

Make sure that the Workstation has been plugged into an active AC outlet for at least 3 hours. If not, plug the Workstation into an active outlet and wait at least 3 hours before performing step 2.

Note:

If the system has been in long-term storage, you should charge the UPS batteries for 6–24 hours.

2.

Power up system as described in Workstation Operator Manual.

3.

Disconnect the USB connector J22 from the top of the electronics box at the rear of the workstation.

23

5.

Verify that the Workstation continues to run for a minimum of seven minutes after you disconnect its AC line plug from the facility's AC outlet. After the system runs for seven minutes, shut the power switch off. The system should go through an intelligent shutdown. Reconnect the USB connector at J22, plug in the UPS and boot the system.

6.

If the UPS does not provide adequate back-up time, replace the UPS per the UPS replacement procedure in this document.

UPS Troubleshooting UPS Troubleshooting Table Perform Test

Failure

Possible Cause

UPS Self Test. (Test initiates upon power-up or when you press the Self-Test button for three seconds.)

The Power On indicator does not glow and the UPS does not start.

Faulty or disconnected UPS power cord.

The UPS operates in battery mode only, even though normal utility power is present.

The input overcurrent protector is tripped. Turn off the UPS. Reduce the load on the UPS and reset the overcurrent protector.

UPS does not provide the expected backup time.

Battery may be discharged because of long-term storage, frequent power outages, or end of battery life. Plug the Workstation into a power outlet and turn the system on for 3 hours to let the battery charge, then press the Self-Test button. If the alarm beeps, replace the UPS. During extended power outages, shut down the system to conserve the battery.

UPS lights flash and/or system beeps.

See the “UPS Fault Indicators” table below.

UPS does not provide back-up power to the Workstation, causing the Workstation to immediately shut down.

Fuse F31 or F32 on the dual passive backplane is open, causing the intelligent shutdown logic on the ISD PC2 PCB to fail. This causes the UPS bypass relays to deenergize and switch the Workstation directly to the AC power input. Because there is no AC power available, the Workstation shuts down immediately.

Failure to perform this adjustment may cause kV overshoots and X-ray tube arcing.

1. If you are installing a new HVSR PCB, turn R83 on the High Voltage Supply Regulator PCB fully clockwise (10 turns max), and then turn it counterclockwise about one turn. This provides an approximate starting adjustment. Otherwise, skip this step. 2. Connect channel 1 of the oscilloscope to TP21 (KV_SEN_TP) on the High Voltage Supply Regulator PCB and channel 2 to TP40 (HI_MA_SEN). 3. Select 8 pps on the Workstation. While taking an HLF X-ray, set the kVp for 40 and adjust mA to 11. Observe the kVp signal at TP21 (KV_SEN_TP) looking for kVp overshoot on the leading edge of the kVp waveform. If kVp overshoot exceeds 400 mV, adjust R83 to reduce it. Repeat this procedure, increasing the kVp by 10 each time until you reach 120 kVp.

Adjustment and Calibration 1. While observing the oscilloscope, adjust R83 for about 400 mV of overshoot--This represents about a 5% overshoot. See waveform in following illustration.

Adjustments and Calibration

400 mV Overshoot Adjustment 2. Re-check mA offset adjustments before doing filament calibration. Note:

Before you perform the next step, perform the Filament/Duty Cycle Calibration in the Adjustment and Calibration section of the 9900 Service Manual.

Note:

The following steps require Digital Cine mode. If the system is not Digital Cine capable, skip steps 6 and 7.

3. Select a Digital Cine Pulse mode (of any available PPS) and a technique of 100 kV @ 100 mA. Monitor TP21 (KV_SEN_TP) on one oscilloscope channel, and monitor TP40 (HI_MA_SEN) on the other oscilloscope channel, using TP49 (HI_MA_SEN_REF) for ground. The two waveforms you see should appear as follows. (The top trace is kV and the bottom trace is HI_MA_SEN.) 4. Repeat the previous step with 120 kV @ 125 mA.

Adjustments and Calibration

Brightness and Contrast Defaults Adjustments for Customizing Profiles Materials Needed • •

laptop service computer with version –14 or greater of Utility Suite installed crossover cable (00-901719-01)

Procedure Although the brightness and contrast levels can be adjusted manually for each separate image, you might also want to adjust the default brightness and contrast settings for one or more profiles. These adjustments can be performed only with Utility Suite build 7.2.11 (00884049-14) or greater. Connect with Utility Suite via the Direct Connect procedure in this manual 1.

Determine which profile or profiles to adjust.

2.

Select five or more images from system memory that represent the clinical usage of the system for each profile to be adjusted. The images should represent a wide variety of anatomies, angulations, and patient sizes.

3.

Rotate the C-arm so that the Image Intensifier is underneath the X-ray tube.

4.

Select a profile to be adjusted. Place a copper filter on the Image Intensifier, take a shot, and save the image. This image will be used to verify that the adjustment has been properly saved onto the system.

5.

Repeat step 4 for each profile to be adjusted.

6.

For each image in a profile, perform the following steps: A.

Recall an image from system memory that was taken using the selected profile.

B.

Press the Auto Contrast/Brightness button on the Workstation keyboard.

C.

Write down the brightness and contrast values, which are located at the upperright of the image, as shown in the figure below.

Example Brightness (Top) and Contrast (Bottom) Values

36

D.

Adjust the brightness and contrast controls on the Workstation until the desired result is achieved.

E.

Write down the new values for brightness and contrast.

Adjustments and Calibration

F. 7.

Subtract the values that you wrote down in step 6.C from the values that you wrote down in step 6.E. These are the adjustment values. Write them down.

After you have determined the adjustment values for a minimum of five images, average the numbers that you derived from step 6.F. The average is the brightness and contrast adjustment value for that profile. Write it down. Consult the table below for an example of how to average the adjustment values.

Repeat steps 6 and 7 for each profile that you want to adjust.

9.

On the laptop service computer, start Utility Suite and perform the Direct Connect procedure in this supplement.

10. Select Anatomical Profile from the RUT View pane. 11. Locate the profile that you want to adjust.

Select a Profile to Adjust 12. Change the brightness and contrast settings by adding the adjustment values that you calculated in step 7 to the current values. For example, if the current brightness value is 0 and the adjustment value is 5, select 5 from the drop-down menu in the Brightness field. If the current brightness value is 3 and the adjustment value is 5, select 8 in the Brightness field. if the current brightness value is 2 and the adjustment value is –5, select –3 in the Brightness field. The same formula applies to the Contrast field. 13. Repeat steps 11 and 12 for each profile that you want to adjust.

37

Adjustments and Calibration

14. From the Utility Suite main menu, select File > Save > To System > Both and follow the prompts to save the files. 15. Reboot the Workstation. 16. Select a profile that was adjusted. Recall the image that you took in step 4 with that same profile and swap it to the other monitor. 17. Place a copper filter on the Image Intensifier, take a shot, and save the shot. 18. Verify that the brightness and contrast values for the shot that you took in step 17 vary from the shot that you took in step 4 by the same amount as the adjustment value, ± 1. For example, if the shot you took in step 4 has a contrast value of 28 and the adjustment value was –5, the contrast value of the shot that you took in step 17 should be 23 ± 1. 19. Repeat steps 16–18 for each profile that you adjusted.

Calibrate Touch Screen Every time you load or reload software into the Workstation, you must calibrate the righthand monitor's touch screen. Follow these steps: 1. Click the Monitor Calibration button in the Utilities Suite list. 2. Click the Calibrate Touch Screen button in the list that appears. 3. When Calibrate Fluoro Track appears, press Yes. 4. Follow the instructions on the right Flat Panel monitor. 5. A Bull's-eye appears in upper left corner of right-hand Workstation monitor. Touch the center of bull's-eye with a finger tip and then lift the finger away from screen. 6. The Bull's-eye moves to lower-right hand corner of screen. Again, touch the center of the bull's eye with your finger and then move your finger away from screen. 7. When you move your finger after step 4, the bull's-eye disappears. This indicates that the touch screen is calibrated. Access an OEC screen on the right monitor to verify proper touchscreen operation. NOTE:

System Software Note:

There are two types of installs that can be performed. A “CLEAN” install will format the hardrive erasing all patient images and system calibration data. You must backup calibration data and all essential patient information. A “NON-CLEAN” install will format the hardrive erasing all system calibration data. Patient images will not be lost. When loading a system software version other than the current version, then generator flash must be erased. Perform the following procedure to install software on the system using a CD. Before you install the system software, verify that the Interconnect cable is connected to the C-arm. Open the Electronics Box at the back of the Workstation and flip the Service switch to the up (service) position.

In the left window of UtilitySuite, select Monitor Calibration. c. Click Calibrate Touch Screen Display. d. The system asks, “Do you really want to calibrate Touch Screen?” Click Yes.

Note:

The connection may be lost before you begin the display calibration. If this happens, continue with the right-screen calibration. The calibration will work anyway. e. On the Workstation, a bull’s-eye appears in the upper-left corner of the right screen. Touch the center of the bull’s-eye with a fingertip and lift your finger away from screen. f.

The bull’s-eye moves to the lower-right hand corner of the screen. Touch the center of the bull’s-eye with your finger and lift your finger away from screen.

g. The bull’s-eye moves to the upper-right corner of the screen. Touch the center of the bull’s-eye with your fingertip and lift your finger away from the screen. h. The bull’s-eye disappears. This indicates that the touchscreen is calibrated. i.

If you get a “Lost Connection to System” message on the service laptop computer, click OK and re-establish the connection of UtilitySuite with the system.

8. If you are working on a Cine system, reformat the Cine drive. a. Launch UtilitySuite and Connect to the System. b. From the RUT menu, select Tools > Cine disk format.

4.

Connect Workstation to AC line.

When you replace the GPOS SBC the 9900 Elite will not boot up fully unless you reload software (either a clean install or normal install.) This is because Linux has the Ethernet MAC addresses stored on the hard disk and requires a match to bring up the Gigabit network (eth1). The new SBC will have different MAC addresses for the two Ethernets, causing bootup to fail. This causes the GPOS to fill up the /var/log/messages files with network errors. The RTOS hangs, waiting for the GPOS DHCP server to provide PXE services for bootup. Reinstalling software formats the disk partitions and cleans up the files that have MAC addresses stored in them. The new addresses are detected and stored during the Linux install procedure.

Functional Tests

Functional Tests The following test supersedes the mA Accuracy Functional Test located in the 9900 Service Manual.

mA Accuracy Note:

This test can only be accomplished using a complete C-arm system with functional system software, as the image chain must be operational.

WARNING:

This test generates X-rays. Take appropriate safety precautions.

1. Place a lead sheet over the Image Intensifier. 2. Place a dosimeter chamber 30cm above the face of the Image Intensifier (as in the entrance dose setup), centered on the grid. As a note, remember that when taking dose rate readings, temperature and barometric pressure scaling factors must be applied for accurate readings. 3. This test provides a functional test of mA by taking a series of exposures at two different kV readings. Successfully performing this test provides a level of functional confidence for both the low mA and high mA sensors. Each series of exposures (at a given kV) starts at 20mA and the mA is successively decreased by half until a value of 2.5mA is reached. Since dose rate scales linearly with tube current, the dose rate is expected to decrease by approximately ½ between successive exposures (at a fixed kV). The 20mA exposure establishes a starting baseline for each series of exposures. Although dose rate will vary from system to system by as much as ±20%, because of tube aging, an approximate baseline for the 100kV @ 20mA exposure is 14R/Min (the first shot in the first series of exposures). If the dose rate differs from this baseline by more than ±20%, further troubleshooting may be necessary, as this implies a deficiency in the generator system. 4. Take the eight exposures listed in the following table. After recording the dose rate, verify that the dose rate is scaling linearly with mA (decreasing approximately by half with a corresponding decrease in mA). Note that although a continuous x-ray mode is used for all exposures, HLF is required for shots with mA values greater than or equal to 10mA.

Video Processing and Display

Video Processing and Display Monitors The Workstation uses two 18-inch, 1-megapixel grayscale LCD monitors designed especially for medical applications. The right-hand monitor is color in systems equipped for surgical navigation. The monitors each have a liquid-crystal display (LCD) with a built in backlight control unit, making them easy to see under a wide variety of lighting conditions. Both monitors operate at the optimum and manufacturer-recommended resolution of 1280 x 1024 pixels. The Workstation has an articulating arm that holds both monitors. The operator can move the monitor pair toward or away from the Workstation, and adjust the height, lateral position and tilt of the monitors with moderate hand pressure. An ambient light sensor and related electronics is mounted on top of the two monitors. This is to detect the room light level and adjust the monitor for optimum brightness under existing light conditions. Note:

130

The ambient light sensor can be enabled/disabled by RUS. At this time, OEC recommends to keep the ALS disabled. This is because of ALS calibration issues. Please note that ALS calibration from RUS is not available for 9900 and therefore, behavior of the ALS operation cannot be changed by re-calibrating the sensor via RUS. Any issues related to poor ALS response from the system could only be resolved by replacing the ALS assembly.
