ABSTRACT:
A method and apparatus for computed tomography. A radiation source and a plurality of scintillation detectors rotate about an analysis plane to measure radiation absorption therein. A like plurality of scintillator elements measure radiation from the source along lines in a reference plane which lines coincide with projections of lines connecting the detectors to the source. Fibre optics adjustably couple light from the scintillator elements to photodetectors associated with the scintillation detectors. A rotating shield alternately shields radiation from the scintillation elements and the scintillation detectors. Compensating signals for system deviations are thus produced.
