Abstract
A scanning method, which is a method of identifying a change in the density of an object, includes arranging a source of ionizing radiation and an array of radiation detectors Dn, where n is an integer from 1 to N, capable of detecting the radiation in such a way that radiation counts are counted by the detectors as the source and detectors are rotated around the object. Detectors are arranged in conjugate pairs so that missing data due to a malfunctioning detector may be filled in from its conjugate.
