x-ray computer tomograph with bilddatenerfassungsschaltung for implementation of high-speed data acquisition

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 (221:22n). The X-ray image signals derived from the plural X-ray detectors (5) are A/D-converted by the corresponding A/D converter units (221:22n) into a plurality of X-ray image data. Then, the X-ray image data obtained from the respective A/D converter units (221:22n) are sequentially transferred via a digital data bus (24) to the image reconstruction unit (30). IMAGE
