COMPUTERIZED TOMOGRAPHY UNIT.

摘要

A computerized tomography unit employing means that is simply constructed without requiring any particular control mechanism to process the data within short periods of time and to measure view data produced by radiated rays of a plurality of photon energy levels through a single scan by a radiated beam. In the computerized tomography unit of the invention, different photon energy characteristics are established between one side and the other side with the center of a multi-channel radiated ray detector as a boundary, the periphery of a sample is scanned in a rotating manner with a fan beam radiated ray, so as to utilize a pair of measured values by radiated rays that pass in the opposite directions through the same portion of the sample.
