Abstract: An X-ray CT photographic apparatus including: a beam shaping mechanism that regulates an irradiation range of an X-ray generated from an X-ray generator and shapes the X-ray into an X-ray cone beam; and a main body controller that changes a read region, where an X-ray detection signal is read in the X-ray detector, according to the irradiation range of the X-ray cone beam. The main body controller changes the irradiation range of the X-ray cone beam to an x-axis direction during an X-ray CT photography such that only a set CT photographic region is irradiated with the X-ray cone beam according to the set CT photographic region input through a CT photographic region setting unit. The main body controller changes a read region in an X-ray detector with respect to the x-axis direction in a detection surface of the X-ray detector during the X-ray CT photography.

Abstract: By turning an X-ray generator and an X-ray detector around a head of a subject, an imaging region is irradiated with an X-ray beam from a plurality of directions to obtain an X-ray projection image. When a center axis X-ray of the X-ray beam passing through a turning center axis is orthogonal to a tomographic layer of interest, the X-ray detector is caused to approach the tomographic layer of interest while the X-ray generator is moved away from the tomographic layer of interest as compared to when the center axis X-ray is not orthogonal to a tomographic layer of interest.

Abstract: The present invention has an object of providing an X-ray CT imaging device which can direct X-ray to an area of interest appropriately even when, for example, the height of the area of interest with respect to the X-ray detector, which is revolving, varies with respect to the revolution direction, and thus can reduce the amount of unnecessary exposure to the X-ray and can perform X-ray imaging of the area of interest with certainty. In an X-ray CT imaging device for performing X-ray CT imaging of a CT imaging area of a subject, during the X-ray CT imaging when a revolving arm is revolving, the expansion in a length direction of an X-ray cone beam, which is to be restricted by length direction blocking plates, is adapted to the shape of the CT imaging area in accordance with the revolution position of the revolving arm.
