An X-ray tomogram imaging device (1) of the present invention is provided with an X-ray tube (31) and a direct conversion-type detector (32). The X-ray tube and the detector are supported so as to be independently rotatable of each other along a curved trajectory by way of support means (21, 311, and 312). Scanning and image reconstruction are performed under instruction from a computer (11). The X-ray tube and the detector are moved independently of each other along the trajectory so that X-ray radiation is consistently transmitted at a desired angle through a desired cross-section of an object to be imaged. A panorama image of the cross-section is generated using frame data, and using the frame data and the panorama image, a tomogram is generated in which the focus in the object to be imaged has been optimized and distortion caused by differences in the angles of the paths of the X-ray radiation has been suppressed. The present invention can be implemented as an apparatus for such applications as medicine, including dentistry, and destructive testing. In addition, the present invention can also have functionality for CT imaging. |
