Abstract
An emission computed tomograph provided with a collimator ring rotatable about an object being examined and having a plurality of slits for defining the direction of incidence of the radiation emitted from the objection the radiation detectors. The slits are arranged circumferentially of the ring and directed at successively different angles relative to the radial direction of the collimator ring, so that as the ring is rotated, the object is tomographically scanned. The collimator ring may be divided into a plurality of equal arcuate portions, in each of which the slits are directed toward the object in parallel with each other, so that as the collimator ring is rotated to scan the object, only the parallel profile data thereof can be obtained.
