Acquired images show defective
pixels
1. Ensure that the tube dose is set to the correct settings.
2. Acquire another image at the recommended median count as
stated in
3. If problem persists; unplug the cables, re-attach the cables,
re-establish the link.
4. If the problem persists, add the defective pixels to the defect
map and redo a gain calibration.
5. Acquire another image.
6. If problem persists, consult the manufacturer or field service
technician for help.
Acquired image does not respond
to exposure or the subject that is
being X-rayed does not show up in
the acquired images
1. Ensure that the tube dose is set to the correct settings.
2. Acquire another image at the recommended median count as
stated in
3. If problem persists; unplug the cables, re-attach the cables,
re-establish the link.
4. Acquire another image.
5. If problem persists, consult the manufacturer or field service
technician for help.
Acquired image shows vertical or
horizontal lines
1. Ensure that the tube dose is set to the correct settings.
2. Acquire another image at the recommended median count as
stated in
3. If problem persists; unplug the cables, re-attach the cables,

6. If problem persists, consult the manufacturer or field service
technician for help.
Residual X-ray image from
previous acquired image shows in
current 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.
