Prerequisites / Notes
NOTE
During maintenance on the product, the work steps in the certificate must be documented accordingly. Maintenance is divided into chapters (as a rule, max. 6 hours for components). Since there can be the same component more than one in a customer system, the component checkpoints in the certificate are listed accordingly. Each component must then be entered with the Part Number and Serial Number. There are also "options" in the customer system. The options must be check marked accordingly in the certificate. With parts that must be replaced periodically (battery/steel cables...), the startup date or the last replacement date must be entered to ensure the ability to track the dates. As a rule, the date can be found in the User Handbook (Handover Protocol / old Maintenance Certificate).

General Remarks
1.2.3.1
Maintenance time / interval The maintenance time and the maintenance interval is listed in each chapter for a component or in the general chapters. The completion times for cyclical replacement of parts, e.g. cables or spring-loaded mechanisms, etc. are not included in these Maintenance Instructions. The work time can be viewed only as a reference value, because the time for e.g. cleaning can vary widely.
1.2.3.2
Tolerance Data General tolerances for linear dimensions per ISO 2768 These tolerances apply for all dimensions listed in these instructions as long as no other tolerance is expressly listed next to the value.

General Visual Check
SI
Checking the cover panels
•
All required cover panels present. - Check the cover panels for visible damage, sharp edges or cracks.
SI
Required operator documents present
•
Are the required operator documents complete, present, legible? - In new systems, there is a list with the documents that are shipped in the System Binder. - Based on this list, completeness can be checked easily. - The following always applies: All required user instructions, supplements and safety notes must be present for use of the system.
SI
Checking the cable corrugated hoses
•
The cables (corrugated hoses) may not have any cracks in the insulation.
•
Check the corresponding strain reliefs or cable shielding connections. - The check refers only to laid cables that are visible and to the way in which they are laid!
SI
Checking the cable corrugated hoses (of mobile components)
•
Check the way in which cables are laid (corrugated hoses) to mobile components. - The cables should not pose a risk of tripping and should not be laid over any sharp edges. - The check refers only to laid cables that are visible and to the way in which they are laid!
SI
Checking the radiation protective panels
•
To the extent configured, visually check the following radiation protective covers for cracks or other damage: - Radiation protection cover panels - Lead rubber flaps - Ceiling-mounted radiation shield - Any additional radiation shields that can be installed - Movable radiation shield
SI
Checking warning labels
•
All warning stickers that indicate a risk (operator, patient or unit) that can occur during operation of the system must be present and legible. - e.g: Crushing of fingers, crushing of feet, laser, maximum load, collision warnings.

General Information WARNING
Even after switching off the radiographic system, electrical voltage is still present in the generator. If not observed, death or serious bodily injury can occur.
PM
Read and observe the warning labels in the cabinets.
Switch power off to the radiographic system and to the on-site power supply and secure them against switching power back on.
Wait until all LEDs in the generator go off (at least 5 minutes).

Checking the High Voltage Cables (with corona disks in the HV transCheck the HV cable shielding.
•
Pull the high voltage cables connected to the high voltage transformer out of the sockets. NOTE
•
Measure the shielding braid against ground; when doing this, move the cable, particularly where it is bent or looped.
Siemens
If the shielding braid is to be grounded in the generator cabinet, remove the grounding cable for the measurement.
Required: maximum 1 Ohm/m
•
If necessary, replace the high voltage cables.
•
Check the high voltage connectors and sockets for damage (burn marks, cracks).

For the screws that are not accessible because of the pinion rack, the “torque wrench attachement, 5660852” absolutely must be used. Otherwise, the screw heads can be damaged.
This check is required only during the 1st maintenance. The documentation applies as proof of securing with Loctite! The the pinion rack mount should be secured with Loctite when installed the first time. In this case, NO check is required. For the check, remove one screw to determine whether LOCTITE has been used; then reinsert the screw with LOCTITE. If LOCTITE was not used, apply LOCTITE to all screws on the pinion rack.

Tomography Direct Technique
QIQ
Checking the Tomo Device For this, the most unfavorable mechanical and electrical tomo and Bucky exposures are made. Using these exposures, the actual tomo height as well as the differences in the resolution power between the Bucky and tomo exposure can be best determined.
•
For Tilting Units: Move the unit into the 0° position.
•
Set the central beam perpendicular to the image receptor.
•
Move the unit into the tomo starting position.
•
Select tomo (max. tomo angle and min. tomo time, e.g. 1.2 sec. 40°).
Description of the Tomo Test Phantom The test phantom is comprised of a hard plastic foam block with 2 slots and two lead strip tests. The two lead strip tests are inserted into the two slots of the hard plastic foam test phantom so that: - the notches are facing to the outside - the lead strip tests do not overlap - the two notches are positioned at exactly the same height above the tabletop. The test phantom is placed on the tabletop so that: - one line test is on the anode side - one axis of the test phantom is parallel to the table longitudinal axis There is a difference in height between each of the holes of 2 mm in the line test that is positioned at an angle of 20º. This makes it possible to exactly determine the tomo height represented on the exposure.

Indirect technique: The surface of the I.I. input screen is concurve. As a result, a reproducible tomo height can be checked only in the center of the I.I. The following procedure describes the test for the direct technique, but it can also be used alternatively in the same manner soweit möglich for the indirect technique.

Evaluating the tomo height on the film. Required: The difference between the set tomo height and the actual tomo height may not exceed 5 mm (the sharply displayed hole on the film corresponds to the tomo height. The holes appear at differences of 2 mm in tomo height).
•
Determining the resolution with Bucky and Tomo exposures. Required: The tomo exposure resolution may be a max. of 1 line group worse than in the Bucky exposure.

The dislayed area dose product must be at least 2-digits; if needed, change the mAs value accordingly and repeat the exposure.

Record the displayed area dose product.
Note:
•
The FDP can also be determined in fluoroscopy mode. Of course, the dosimeter must then be set to a dose measurement range and not to a dose rate.
Calculate the radiation field size A in cm2. Since collimation was to a radiation filter, approximately the following results: - with square collimation, 310 cm2 - with 8-sided collimation, 248 cm2
