CT scanner with reduced radiation doses
Description
A CT scanner having a rotating X-ray source and a stationary circular array of 600 contiguous detectors is described. It includes a sliding shutter mechanism incorporated in the precollimator system that prevents detectors at the beginning and at the end of a scan from receiving radiation while progressively increasing and decreasing, respectively, the current to the X-ray tube.
