摘要： In an X-ray CT imaging, an X-ray generator (11) and a two-dimensional X-ray detector (21) are opposed to each other between an object and are rotated by a rotary shaft (32) around the object. At least one of the rotary shaft supporter (61) and an object holder (40) includes a movement mechanism (42, 65) for moving a supporter (30) for the X-ray generator and the X-ray detector relative to the object. In offset scan CT imaging, the rotation of the supporter by the rotary shaft is performed simultaneously with the relative two-dimensional movement of the rotary shaft by the movement mechanism. In the relative two-dimensional movement, the position of the rotary shaft is moved according to the rotary angle of the supporter along a circular orbit around the center of a CT imaging region in a plane crossing the rotary shaft. Thus, it becomes possible to image a larger region of interest of the object.

摘要： An X-ray imaging apparatus includes an X-ray generation part, an X-ray detection part, and a revolution drive mechanism. The X-ray generation part has an X-ray generator including a cathode and an anode, and emits an X-ray beam from the X-ray generator. The X-ray detection part detects the X-ray beam. The revolution drive mechanism performs X-ray imaging by revolving the X-ray generation part and the X-ray detection part around the object while the X-ray generation part and the X-ray detection part are opposed to each other with said object interposed therebetween. The X-ray imaging apparatus controls a restriction part to thereby restrict an X-ray transmission in such a manner that the focal spot size of an X-ray beam used in X-ray CT imaging of a relatively narrow imaging region is smaller than the focal spot size of an X-ray beam used in X-ray CT imaging of a relatively large imaging region.
