Abstract
An X-ray photographing device comprising a turning means for turning an x-ray source and an X-ray sensor around a subject is provided with an arcuate movement means for arcuately moving the X-ray sensor around an arcuate movement center axis, and a control unit. The control unit continuously performs a first photographing step for detecting an X-ray flux while turning the X-ray sensor in a first arcuate movement range around the arcuate movement center axis by the arcuate movement means, a shifting/turning step for shifting/turning an arcuate movement arm around the subject by the turning means, and a shifting/photographing step for detecting the X-ray flux while turning the X-ray sensor in a second arcuate movement range around the arcuate movement center axis by the arcuate movement means in the state shifted from the first arcuate movement range by a very small angle in the shifting/turning step.
