Method and apparatus for measuring radiation in computer-assisted tomography and radiographic applications

摘要

An apparatus for determining the intensity of radiation passing through an object as a set of planar beams from a radiation source is disclosed. The radiographic apparatus includes a detector array of adjoining scintillators having wall linings suitable for absorbing radiation, thereby functioning as self-colliminating detectors. The apparatus is also capable of counting the number of individual photons of primary radiation passing through an object along each path from a radiation source operating at the very high count rates used in computer-assisted tomography applications.
