areas") by the FW/SW V1.0 are present within the system in an
unchanged format. EEPROMs, containing such settings, aren't
supposed to be replaced in course of this upgrade. Since, however, in course of some work steps the detector has been
removed and the connection of the OPDIMA option was made
available, following activities have to be performed additionally:
1) Rotation test/check.
2) Calibration/check of the optimized compression for OPDIMA;
(or, setting of that parameter to the same value as for the DR).
3) Calibration of the collimator for the radiation beam and the light
field.
4) Calibration of the wing difference; (or , setting of that parameter
to the same value as for Mo large focus).
5) Disabling film exposure, i.e. the setting of the "Allow film exposure" software switch to OFF.
6) OPDOSE - Configuration of "Auto limits" for both, DR (Digital
Radiography) and for the OPDIMA.
7) Check of the grid lines.
8) Calibration of the detector gain.
Rotation Test 4
• Move the wing in different positions and watch to the cable.
• The rotation of the swivel arm has to stop on position 0°, + 45°, + 90° and + 120°, when
OPDIMAr wing is selected.
• The rotation of the swivel arm has to stop on position 0°, + 45°, + 90° and + 135°/ - 180°,
when Detector wing is selected.
• Installing the wing cover and the bellow.

Checking the OPCOMP function when Opdima wing selected 4
• Decompress.
• Set the compression force to 20 kg by using the presetting knob and compress.
The compression movement must be interrupted by OPCOMP before 20 kg is reached,
i.e. at 5-15 kg depending on the material used.
• Adapting OPCOMP.
NOTE
NOTE
If the factory-set OPCOMP is not to the customer's satisfaction,
an adjustment can be carried out with the tautness factors in the
"Optimized compression dr" table, see Service Instructions (Software, SPB7-250.816.03...). A lower tautness value will increase the
compression force and vice versa. Increase/decrease the tautness factor by e.g. 10 the first time. Let the customer use this setting for at least two weeks before further changes are made.
OPCOMP has been thoroughly tested by Siemens. If any factors
are changed, OPCOMP will no longer be an optimization of compression force and image quality according to Siemens' clinical
test.
Collimator checks 4
• Checks have to be performed according to the chapter Collimator Adjustments of the
corresponding Startup with WH AWS, from System Serial No. 1101 SPB7-250.815.03...
Collimator wing difference Calibration 4
Select the OPDIMAr wing by moving the detector in the parking position. OP is then displayed on the control console.
• Connect the compression plate simulator and the collimator-mounted plexi phantom.
• Start the service software on the service PC and select:
Configuration -> Collimator -> Calibration of wing difference
NOTE
If no precise wing difference calculation is performed, or if you have to start from scratch,
you can start with the "large focus/molly" values that have been adjusted with the
"Collimator beam calibration".

Fig. 21
• Enter the numbers in the table below:
• Narrow the X-ray field so that the edges of the detector will not be exposed to the X-ray
and white lines are visible in the image at the edges of the detector. To do this, decrease
the YC value and increase the YS, XR and XL values by 5 numbers.
• Make sure a patient is registered and start an exposure.
• Use a magnification of 4 in the application software and go to the edges of the detector.
White areas should be visible at all edges of the image. This shows you that the X-ray
does not cover the entire detector and shows where the beam really ends.
• Measure the white line thickness at each image edge with the application graphical user
interface and adjust the corresponding XL, XR, YC and YS values with the service
software.
• Start an exposure.
• Check if the white lines at the edges of the image are gone using a magnification of 4 in
the application graphical user interface.
• Save the calibration and Exit from the Service Software.
NOTE
If you see a white thin line on the chest wall when using the magnification.
table, it might be the magnification table itself. Move the magnification table out by approximately 1 mm and try again.
