Abstract:
1. A system for detecting positrons emitted from radio-labeled sites within a body, said system comprising a detector assembly therein for identifying the location of the radio-labeled site within the body, said detector assembly comprising one or more sheets of radiation detectors positioned around the body so as to intercept annihilation photons resulting from positron emissions from within the body, said one or more sheets of radiation detectors comprising: a) multiple silicon photomultipliers attached to one or more scintillators to form array, said array constituting a plane, b) multiple arrays stacked in a direction perpendicular to the plane of the array to form a three dimensional radiation detector module, and c) multiple radiation detector modules arranged to form a two dimensional flexible sheet of multiple radiation detector modules, wherein, the system is arranged for placement around and conforming to a portion of the body being examined, said portion of the body comprising the head, breast, a limb or the pelvic region.
