ABSTRACT:
An X-ray data collecting apparatus includes a first integrating means periodically executes sequential integration on detected signals from a plurality of X-ray detector elements corresponding to measurement channels in an X-ray detection apparatus at a constant time difference over a constant time period longer than the time difference; a second integrating means periodically executes sequential integration on detected signals from a plurality of X-ray detector elements corresponding to reference channels in the plurality of detector element rows in the X-ray detection apparatus at the same time difference as the constant time difference over the same time period as the constant time period; and a correcting means X-ray-dose corrects signals integrated by the first integrating means by signals integrated by the second integrating means that are integrated at the same time as the signals integrated by the first integration means, respectively.
