ABSTRACT:
A positron emission tomography camera having a plurality of scintillation crystal planes positioned side-by-side around a patient area to detect radiation therefrom and forming 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 slanting light guides are positioned between the crystals and the coacting detectors. The light guides are equal in number to the crystals and have a first end adjacent to one crystal and a second end positioned adjacent the detectors. The second ends of the light guides are axially offset in the rows a different amount from each other for providing an identification to the detectors of which crystal detects radiation.
