Table 16
Problems and Solutions (Continued)
Acquired image does not respond
to exposure or the subject that is
being X-rayed does not show up in
the acquired images
1.
Let power-off (
Section 11.7
) or reboot the detector (
Section 11.8
),
re-insert the battery re-establish the link.
2.
Ensure that the tube dose is set to the correct settings and that
the detector is in the path of the X-ray beam.
3.
Acquire another image at the recommended median count as
stated in
Section 11.12.3
.
4.
Ensure that the X-ray detector is in the X-ray Beam path.
5.
If problem persists, consult the manufacturer or field service
technician for help.
Acquired image shows vertical or
horizontal lines
1.
Let power-off (
Section 11.7
) or Reboot the detector (
Section
11.8
), re-insert the battery, re-establish the link.
2.
Ensure that the tube dose is set to the correct settings.
3.
Acquire another image at the recommended median count as
stated in
Section 11.12.3
.
4.
If the problem persists, add the defects to the defect map and
redo a gain calibration.
5.
Acquire another image.
6.
Move the X-ray detector away from any device that may
introduce noise.
7.
If problem persists, consult the manufacturer or field service
technician for help.
Residual X-ray image from previ-
ous acquired image shows in cur-
rent acquired image
Charge on the sensor pixels from an exposure beyond the
saturation point of the pixels may cause a residual image. It can be
erased by increasing time between exposures or taking multiple
images until the artifact fades away.
