Abstract
By turning an X-ray generator and an X-ray detector around a head of a subject, an imaging region is irradiated with an X-ray beam from a plurality of directions to obtain an X-ray projection image. When a center axis X-ray of the X-ray beam passing through a turning center axis is orthogonal to a tomographic layer of interest, the X-ray detector is caused to approach the tomographic layer of interest while the X-ray generator is moved away from the tomographic layer of interest as compared to when the center axis X-ray is not orthogonal to a tomographic layer of interest.
