An X-ray tomographic imaging apparatus includes an X-ray and a direct conversion type of detector. The X-ray tube and the detector are supported by the support means so as to be rotatable along curved orbits mutually independently. Under instructions from a computer, scans and image reconstruction are performed. The X-ray tube and the detector are moved along the orbits mutually independently so that X-ray beams are always transmitted through a desired tomographic plane of an object at desired angles. Acquired frame data are used to produce a panoramic image of the plane, while the frame data and the panoramic image are used to produce a tomographic image in which structural components of the object are optically focused and distortions caused due to differences in X-ray paths are suppressed. The apparatus can be used as devices for dental, medical diagnosis and nondestructive inspection, and can have a CT imaging function.
