Abstract
An X-ray imaging apparatus includes an X-ray collimator control unit which controls an X-ray collimator shape, an X-ray irradiation unit which irradiates X-rays in accordance with the X-ray collimator shape, an X-ray imaging unit which receives the irradiated X-rays and acquires a radiograph, a perpendicularity determination unit which determines, on the basis of the comparison between the X-ray collimator shape and the radiograph, whether the X-ray irradiation direction of the X-ray irradiation unit is perpendicular to a light-receiving surface by which the X-ray imaging unit receives the X-rays, and an irradiation control unit which controls X-ray irradiation by the X-ray irradiation unit on the basis of the determination result obtained by the perpendicularity determination unit.
