Abstract
Timing and energy resolutions of the Bi4Ge3O12 scintillation crystals were studied, with particular respect to a positron-camera application. In comparison with the NaI(Tl) system, the detection efficiency for annihilation radiation was more than triple and coincidence detection efficiency was more than 10 times as good. The properties of the new scintillator material and their bearing on the spatial resolution and the efficiency of coincidence detection in positron cameras with stationary ring detectors were studied.
