High speed computer assisted tomography |
摘要 |
X-ray generation and detection apparatus for use in a computer assisted tomography system which permits relatively high speed scanning. A large X-ray tube having a circular anode (3) surrounds the patient area. A movable electron gun (8) orbits adjacent to the anode. The anode directs into the patient area X-rays which are delimited into a fan beam by a pair of collimating rings (21). After passing through the patient, X-rays are detected by an array (22) of movable detectors. Detector subarrays (23) are synchronously movable out of the X-ray plane to permit the passage of the fan beam.
