    摘要： In an X-ray CT (computerized tomographic) imaging system (100), there are mainly provided a plurality of X-ray detectors (5), data acquisition circuitry (20) and an image reconstruction unit (30). The data acquisition circuitry (20) includes a plurality of A/D converter units (22₁:22 n ). The X-ray image signals derived from the plural X-ray detectors (5) are A/D-converted by the corresponding A/D converter units (22₁:22 n ) into a plurality of X-ray image data. Then, the X-ray image data obtained from the respective A/D converter units (22₁:22 n ) are sequentially transferred via a digital data bus (24) to the image reconstruction unit (30).

    摘要： A positioning unit for a radiation tomography apparatus characterized in a light beam detector (34) and a light beam generator (32) which are disposed opposite each other on a horizontal line (L) passing through the centre of a photographing region irradiated by X-rays, a table top (36) on which a patient (P) is laid, a driving device (38) for driving the table top (36) in the vertical direction, a position detector (40) for supplying a signal the magnitude of which corresponds to the position of the table top (36); and a controller (44) which obtains data corresponding to the distance from an upper surface of a part of the patient (P) to the horizontal line (L) of the photographing region, based on an output signal of the light beam detector (34) and an output signal of the position detector (40).
    In accordance with the distance data and data corresponding to the horizontal line (L), the controller (44) energizes the driving device (38) until a signal corresponding to the desired distance data is supplied by the position detector (40).
