摘要： An X-ray imaging system that allows X-ray images to be acquired from a desired direction by considering the tilt of a tabletop. The X-ray imaging system includes a support unit that holds an X-ray imaging unit that performs X-ray imaging of a subject. The subject is placed on the tabletop. A memory stores in advance imaging angle information from previous imaging. A tilt detector detects the tilt angle of the tabletop. A calculator calculates a correction angle for correcting the imaging angle information based on the imaging angle information and on the tilt angle. A drive unit moves the support unit to a position based on the imaging angle information and the correction angle.

摘要： When a tabletop is rolling, an aperture specifying unit calculates an aperture of diaphragm blades such that a radiation field is to be R′ based on a rolling angle, where R′ is a radiation field having the same radiation area of X-rays after tabletop rolling as a radiation area before the tabletop rolling. The aperture specifying unit instructs a beam-limit control unit to take the calculated aperture of the diaphragm blades in an X-ray beam limiting device. Then, the beam-limit control unit controls the aperture of the diaphragm blades such that the radiation field is to be R′.
