Claim of US Patent No. 9,392,988

8. A non-transitory computer readable storage medium that stores a computer program for causing a computer to serve as a control
device of an X-ray imaging apparatus that performs X-ray radiographing by detecting X-rays that transmitted through an object
with an X-ray sensor, the X-ray imaging apparatus comprising:
an acquisition unit configured to acquire information related to an image lag component of the X-ray sensor; and
a control unit configured to perform a drive application to alter a bias voltage on elements of the X-ray sensor by a bias
power source for each radiographing operation before an amount of the image lag component become stable,

wherein the control unit performs radiographing operation without performing the drive application after the amount of the
image lag component becomes stable.
