Abstract
In a computerized tomographic radiographic apparatus a source of radiation projects radiation through a patient to be incident on at least some of a plurality of detector devices. To project the radiation from different directions the source moves relative to the body and also relative to the detectors to irradiate different detectors. Collimators, moving with the source, are provided to reduce the incidence of scattered radiation on the detectors. The collimators take the form of baffle plates which are arranged, to present substantially the same exit aperture to each detector despite the relative movement.
