摘要： In an X-ray imaging apparatus that performs X-ray CT imaging, an X-ray generator (13) that generates an X-ray cone beam (BX1) and an X-ray detector (21) that detects the X-ray cone beam (BX1) radiated to an object (specifically, image object (OB)) are revolved for 180 degrees to be opposed to each other with the object being located therebetween. Further, the X-ray generator (13) is moved such that a revolution reference point (CP) that is set on an optical path (CB) of the X-ray cone beam (BX1) goes round of a predetermined oval shape while the X-ray detector (13) and the X-ray generator (21) are revolved for 180 degrees. Setting is made such that a CT image area (CA) to be imaged by the irradiation of the X-ray cone beam (BX1) has an approximately triangular shape through the above-mentioned operation.

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： There is provided a new X-ray imaging apparatus by the use of which X-ray CT and panoramic imaging can be effectively performed. In an X-ray imaging apparatus which rotates an X-ray generating section and an X-ray detecting section around an imaging object arranged between these X-ray generating section and the X-ray detecting section and also detects in the X-ray detecting section X-rays having been radiated from the X-ray generating section and transmitted through the imaging object to form an X-ray image, a panoramic imaging mode in which the X-ray generating section and the X-ray detecting section are driven to form a panoramic image of the imaging object and an offset scan/CT mode in which the X-ray generating section and the X-ray detecting section are driven to form a tomographic image of the imaging object are set, so as to selectively execute these two imaging modes. Consequently, the panoramic imaging mode and the offset scan/CT mode can be arbitrarily selected, thereby allowing formation of an X-ray imaged image that is optimum for treatment.
