摘要： In the imaging space provided by a panoramic imaging apparatus, a phantom is arranged. The phantom is located to a predetermined tomographic plane and includes markers which image known positional information with an X-ray beam. The X-ray beam from an X-ray source is acquired as X-ray transmission data by a detector, and a panoramic image is produced using the data. Based on known positional information of the markers and information of marker positions in the panoramic image, distance information (Rs, Rd) between the X-ray tube and the detector and height information (B1) of the X-ray tube to the detector are calculated. From this calculated results and the acquired data, parameters (Δx/ΔFi, θ, Δθ/ΔFi, D, A, CX, CY) defining positional relationships among the X-ray tube, the detector, and the tomographic plane are calculated such that amounts of changes in the position connecting the X-ray tube and the detector are considered in the parameters. This allows the parameters to be calibrated for 3D image reconstruction.

摘要： 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.
