Explanation
This error indicates that the aver-
age signal level of the pre-expo-
sure image is too high to
calculate the X-ray parameters
for the exposure.
This error indicates that no glan-
dular region was found.
This error indicates that AOP
Image Quality can not be
ensured, because the breast
thickness is outside the AOP
thickness range of 0 cm - 9 cm (0
to 3.5 inches).
AWS set-up in progress (loading
of Flat Field map) after a new fil-
ter was selected.

Corrective Action
Switch to Manual mode, or ensure that conditions
are correct for use of AOP.
When using AOP:
- Ensure that the breast extends into the AOP
sensing zone.
- Verify that the breast thickness is shown as
greater than 0 cm on the Gantry Readout.
If the problem recurs frequently after taking the
above precautions, note ALL messages and inform
GEMS Field Service.
- Do not use AOP if the breast thickness exceeds
9 cm (3.5 inches).
- Verify that the breast thickness is shown as
greater than 0 cm on the Gantry Readout.
- Ensure that the breast extends into the AOP
sensing zone.
- Ensure that no highly attenuating objects (mark-
ers larger than 2 mm2, needles, etc.) are inside
that AOP sensing zone.
- Ensure that the compression force and thickness
measurements are correctly calibrated.
- Do not use AOP if the breast thickness exceeds
9 cm (3.5 inches).
- Verify that the breast thickness is shown as
greater than 0 cm on the Gantry Readout.
- Ensure that the breast extends into the AOP
sensing zone
- If the breast is too thick, or it can not be posi-
tioned in the AOP sensing zone, use manual expo-
sure control.
No action required.
