X-ray computerized tomographic image data acquisition circuitry capable of performing high-speed data acquisition

摘要

In an X-ray CT (computerized tomographic) imaging system, a plurality of X-ray detectors, data acquisition circuitry and an image reconstruction unit are provided. The data acquisition circuitry includes a plurality of A/D converter units. The X-ray image signals derived from the plurality of X-ray detectors are A/D-converted by the corresponding ones of the A/D converter units into corresponding X-ray image data. Then, the X-ray image data obtained from the respective A/D converter units is sequentially transferred via a digital data bus to the image reconstruction unit.
