  • Patent number: 10076291
    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.

  • Patent number: 8817944
    Abstract: 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.
