ABSTRACT:
An array of radiation detectors is rotated about one or more sources of fan-shaped substantially planar radiation beams which are, in turn, rotated in the opposite direction about a three-dimensional body such that substantially parallel paths are defined between given individual detectors of the array and the radiation sources during the course of their oppositely directed movements. Radiation absorption measurements are taken along thusly defined plural intersecting sets of substantially parallel paths within a desired cross-section of the three-dimensional body to provide data for use in computing and displaying a constructed visual image of structures having different radiation absorption coefficients within the cross-section.
