8 COMPLETION
If no Generator parameter backup is available, or the restore is not successful, the Generator must be
reconfigured. If Generator reconfiguration is necessary:
• Carry out the following calibrations:
Calibrations - Checks
Acquisition Image Chain
Heating Current Calibration
Bias Calibration
Tube mA Measurement
kV Scale Factor
mAs X-ray Calibration
Bad Pixel Calibration
Gain calibration
flat field tests
Half Value Layer
Conversion Factor
AOP: Automatic Optimization of Parameters
AOP Calibration
mAs non linearity
AOP/SNR Check
If AOP/SNR Test not OK, repeat all calibrations from AOP Calibration.
• For Senographe systems that use AWS V43.0 or later (on the SB150) or AWS 53.0 or later (on
the U20), or AWS 54.10 or later (on the Z400), if the Senographe system does not use the default
AOP Classic (AOP A) tables configuration, restore as necessary the AOP configuration (see
Card ELE A031 - AOP Configuration on page
• For Senographe systems that use AWS 53.40 or later, which have the Stereotaxy option installed
and do not use the default AOP Profile (AOP B) tables for AOP stereo mode, restore the AOP stereo
Configuration according to Job Card IST A003 AOP Configuration, as described in the Senographe
DS Stereotaxy Service Manual.
