ABSTRACT:
In a computerized tomographic CT scanner, a lateral scan of a pencil beam of radiation is effected by causing an apertured, annular collar to rotate around a source of a fan-shaped spread of radiation. The motion of the collimator causes a pencil like beam to sweep angularly across the body. Successive sweeps, caused by successive apertures, are in the same direction.
