An X-ray photography apparatus including: a turning arm that supports an X-ray generator and an X-ray detector which are opposed to each other so that the head of a patient can be interposed therebetween, and a moving mechanism that includes a turning part and a moving part. The turning part turns the turning arm about a turning axis with respect to the head. The moving part moves the turning arm relative to the head in a direction perpendicular to the turning axis. The X-ray photography apparatus also includes: an image processor that generates an X-ray image, a photographic region designation part that designates part of a row of teeth along a dental arch as a pseudo intraoral radiography region, and an X-ray forming mechanism that changes the irradiation direction in which the head is irradiated with an X-ray relative to the axial direction of the body axis of the patient. |
