Abstract
A positron emission tomography camera having a plurality of crystals and planes which are positioned side-by-side and form adjacent rows of crystals transverse to the planes. Each row of each plane has a plurality of crystals and a row of light detectors are positioned adjacent each row of crystals. A row of reflecting masks are positioned between each row of crystals and each row of coacting light detectors and coded for providing an identification to the detectors of which crystal detects radiation. In addition, the ends of the crystals have a frosted finish and the sides have a polished finish for increasing the optical efficiency.
