READ THIS FIRST

Using This Manual:

A person who will be performing service work on the PRODIGY should use this manual in the following

manner:

Read the Safety and Overview Chapters to familiarize yourself with the scanner as a whole and with the

general function of the circuit boards.

Chapter 3 should be understood completely as it explains the Diagnostics Software (built in – requires a

password for access).

The Chapter 4 and Chapter 5 contain common procedures and troubleshooting information and can be

read as needed, but are good sources of information.

When a problem arises, Chapter 4 should be referenced. Check the table of contents for Chapter 4 to see

if the problem being experienced is described. If so, refer to the appropriate page. If not, try to generalize

the problem (e.g. the Detector is repeatedly running into the front of the scanner and reversing and then

running back into the front of the scanner. This is a mechanical problem in general, specifically with

Transverse Mechanics, check that subsection of Chapter 4 for the subsystem experiencing the fault.

This manual commonly references other Sections and pages of the manual as needed, so often

procedures in Chapter 5 and the Appendix are referred to as ways to solve problems described in

Chapter 4.

1.0 General Safety

• DO NOT attempt to service the PRODIGY without first reading this manual.

• DO NOT attempt any repairs without prior instructions from authorized LUNAR personnel.

• In order to maintain electrical safety and electromagnetic compatibility, the Lunar PRODIGY is

only to be connected to a computer, printer, and peripherals that are certified to be compliant

with IEC 950/EN 60950 Safety of information technology equipment, including electrical business

equipment and IEC 601-1-2 Medical electrical equipment, Part 1: General requirements for safety,

2. Collateral Standard: Electromagnetic compatibility - Requirements and tests. Emergency Stop

Button.

• Ionizing Radiation Exposure: When power is applied, this equipment may generate ionizing

radiation. Take precautions that no part of the body passes through the x-ray beam when the

equipment is energized. Avoid scatter radiation during warm-up and testing by maintaining a

safe distance from the x-ray beam. See the Safety and Specification manual for equipment

appropriate distance and other precautions regarding ionizing radiation. All operators must be

properly trained regarding ionizing radiation and take adequate steps to protect against injury.

• Electric Shock: This equipment contains high voltages. When the tabletop/panels/ shrouds are

removed, visually confirm that power cord is unplugged and remains unplugged until power is

required to complete the procedure. When servicing while energized, take precautions to prevent

electric shock.

• Moving Parts and Pinch Points: Avoid moving parts and pinch points (e.g. belt/pulley, arm/back

rail, green wheels/rail).

• Sharp Edges: Take precautions to prevent injury from contact with component edges (e.g.

OMI/OMD wheel, arm slot cover).

• Hot Surfaces: Keep hands clear or allow components to cool before servicing. (e.g. stepper

motors, hard drives, power supplies and microprocessors).

• Heavy Lifting: Obtain help lifting or moving any object weighing over EHS limits. Ask for

assistance when maneuvering awkward objects (e.g. tabletop).

• Laser Radiation: Do not stare into the laser beam at any time. The reflection from the tabletop

or shutter/collimator assembly is sufficient to determine if the laser is on.

• Follow appropriate Lockout/Tagout procedures as described in MyLearning training course

GEMS-EHS-LOTOAth.

• Wear appropriate PPE (Personal Protective Equipment) while servicing the equipment, e.g. eye

protection and steel-toe/composite-toe shoes.

1.2 Emergency Stop Button

The Emergency Stop Button is a round red button located on the scanner display panel (see Figure 1-1).

When pressed, power is removed from the X-ray tube head, the laser, and the shutter is closed. Power is

also removed from the scan arm motors, allowing the operator/patient to push the scan arm out of the

way.

1.3 Laser Exposure

The PRODIGY is equipped with a Class II Laser device. This laser is used for patient positioning. A Class II

rating indicates a low power visible laser that is not normally hazardous to eyesight but has the potential

to be hazardous if viewed directly for an extended period of time. Because of this potential hazard, DO

NOT stare directly into the beam while the laser is in operation, and DO NOT allow the beam to shine

directly into the patients' eyes. No specific eye protection is required with a Class II laser.

A amber laser-on indicator, located on the front of the scan arm, is lit when the laser is on. The program

activates the laser during positioning for an image acquisition. The program then turns off the laser

when you begin the scan. The emergency stop button will turn off the laser.

There is a caution label (Figure 1-2) on the scan arm near the Display Panel.

Figure 1-2. Laser Warning Label (U.S. systems only)

Note: DO NOT STARE INTO THE BEAM while the laser is operating.

1.4 Shutter Indicator

This symbol is used to indicate an open-shutter condition in accordance with the safety standards

established by the International Electrotechnical Commission (IEC).

Figure 1-5. S ou r c e ( x-rays) off - Shutter closed (green)

Figur e 1 -6 . So u r c e (x -rays) on - Shutter open (yellow)

This symbol appears near the yellow X-ray shutter-open indicator light. The X-ray shutter-open indicator

light is located on the Display Panel on the scan arm near the front.

Note: When the x-ray on / shutter open symbol appears in literature associated with the PRODIGY scanner,

it will be used to indicate that the procedure being described results in an open shutter condition. During

these times personnel should exercise caution to avoid excessive exposure t o th e X -rays.
