摘要：

To provide a technique of acquiring a high-resolution X-ray projection image without interfering with turning of an X-ray generator and an X-ray detector. By turning an X-ray generator 42 and an X-ray detector 52 around a head of a subject M1, an imaging region ROI is irradiated with an X-ray beam BX1 from a plurality of directions to obtain an X-ray projection image. When a center axis X-ray CBX1 of the X-ray beam BX1 passing through a turning center axis RA1 is orthogonal to a tomographic layer of interest LOI, the X-ray detector 52 is caused to approach the tomographic layer of interest LOI while the X-ray generator 42 is moved away from the tomographic layer of interest LOI as compared to when the center axis X-ray CBX1 is not orthogonal to a tomographic layer of interest LOI.
