Abstract:
1. An X-ray CT imaging method for performing X-ray CT imaging comprising: a supporting step of supporting an X-ray generator that generates an X-ray cone beam, and an X-ray detector that detects the X-ray cone beam radiated to a subject by a support part with the subject located therebetween; a revolving step of revolving the support part relative to the subject by a revolution driving part in the supporting step; a moving step of moving the support part relative to the subject on a two-dimensional plane orthogonal to a revolution shaft of the revolution driving part by movement mechanisms in the revolving step; and a controlling step of controlling the revolution driving part and the movement mechanisms in an interlocking manner such that a CT image area has an approximately triangular shape, the CT image area being imaged by irradiation of the X-ray cone beam by revolving the support part in the revolving step.
