018-234-06E
Occurrence Condition
[During full calibration]
Gain correction data generation cannot take place due to excess or
insufficiency of X-ray irradiation and insufficiency of the irradiation field.
[During M-Utility]
An attempt is made to carry out gain calibration but results in failure.
<Reference>
You can check the FPD No. of interest, and the conditions of the dose
and the irradiation field under which the gain correction data cannot be
generated on the error log.
[During bootup]
The values of a total defective pixel count, continuous defect lines
and a total defective line exceeding the specifications are detected in
defect correction data generation of background calibration (calibration
automatically taking place when the CU starts up).
[During full calibration]
The values of a total defective pixel count, continuous defect lines and
a total defective line exceeding the specifications are detected in defect
correction data generation.
<Reference>
You can know the No. of the FPD of interest and in which specifications
the error is detected on the error log.
[During full calibration]
Although an attempt is made to start gain calibration with exposure or
defect calibration, the calibration cannot take place since the grid is
detected to be mounted.
[During full calibration]
After gain calibration is to take place, the number of exposures necessary
for the gain calibration is recognized to be insufficient.
<Reference>
Sixteen exposures are necessary to carry out the gain calibration.
[During full calibration]
After defect calibration is to take place, the number of exposures
necessary for the defect calibration is recognized to be insufficient.
<Reference>
Five exposures are necessary to carry out the defect calibration.

Probable Cause and Remedy
The following cases are being considered.
1. The exposure conditions (kV, mAs, SID) are
inappropriate, and the dose is insufficient.
2. T he dose is sufficient, but the irradiation field is
narrow, and the entire panel is not being irradiated
with X-rays.
3. T he dose and field are both normal, but the TFT is
splitting and no signals are being output from some of
the regions.
In the case of 1, measure the dose with a dosimeter.
In the case of 2 and 3, check the images which were
exposed under the calibration and same conditions, and
check whether the X-rays are being recognized in the
assumed regions.
- Check the FPD.
- Check the grid.
- Check the exposure count.
- Continue exposures until the necessary exposure count
for the gain calibration is reached, and click [Create a
Gain Data].
- Check the exposure count.
- Continue exposures until the necessary exposure count
for the defect calibration is reached, and click [Create a
Gain Data].
