Abstract
A CT scanner having an outer circular array of stationary radiation detectors for an inner concentrically revolving source of radiation emitted in a fan pattern subtending a number of the detectors. Each grouping of 15 consecutive detectors is housed in a detector module, each one of which is provided with an electro-optical device which is arranged to normally deactivate the output of each of the detectors in the module. The detectors are arranged in exclusive groups of four nonconsecutive detectors each equiangularly disposed about the array connected in daisy chain fashion with the output of each of said nonconsecutive detector groups applied to a single signal cable defining a corresponding signal processing channel. There is also provided an opaque vane arranged for rotation in fixed relation to said revolving source of radiation for temporarily interrupting the deactivation caused by each of the electro-optical devices which correspond to those detectors in the array which at any time are being irradiated by said source.
