Abstract
A CT image processor for use in X-ray computerized tomographic system including an X-ray source for providing fan beams on an object being examined, a multichannel X-ray detector for detecting the fan beams transmitted through the object and a processor for reproducing a sectional image of the object including circuitry for obtaining a back projection of the signal obtained from the multichannel radioactive ray detectors, the processor circuitry also having means for rearranging the order of the fan beams into parallel beams and for effecting scaled-up interpolative operations based on the projected image signal so as to use the scaled-down interpolated data for the back projection.
