ABSTRACT:
An X-ray photography apparatus includes a photographing system and a movement control section. The photographing system is made up of a normal X-ray source for irradiating X rays to a subject, a small focus X-ray source for irradiating X rays to the subject, and an X-ray detector for obtaining an image signal by detecting X rays transmitted through the subject. The movement control section moves and controls at least one component from among the normal X-ray source, the small focus X-ray source, and the X-ray detector so that the arrangement of the photographing system is switched between a first arrangement suitable for normal photography in which the subject is photographed employing the normal X-ray source, and a second arrangement suitable for magnified photography in which the subject is magnified and photographed, employing the small focus X-ray source.
