ABSTRACT:
The method of determining collimator aperture efficiency for a computerized tomographic scanner having a plurality of radiation detectors positioned along a detector arc, a source of radiation having a focal spot having radiation flux distribution positioned across a scan circle from at least part of the detector arc, and a collimator having a plurality of apertures arranged in a collimator arc around said source.
Also disclosed is a tomographic scanner having a circular detector arc, a radiation source moveable along a circular arc and an arcuate collimator having apertures in which the width of the collimator aperture in the geometry of the system has high efficiency. The ratio of the detector radius to the source radius, to the collimator radius, to the aperture width is 36:24.3;9.4:0.024.
