Abstract
In a computerized tomographic apparatus in which the source and detectors are moved angularly around the body, the angular movement of the source is, in effect, periodically arrested so that the detectors, which are of greater angular extent than the distribution of radiation produced by the source, slide through the distribution. In this way successive detectors can be made to view the same beam in the distribution.
