Abstract
A PET scanner includes a ring of detector units which receive gamma rays produced by annihilation events. Each detector unit includes a 6.times.6 array of BGO scintillation crystals mounted in front of a 2.times.2 array of photomultiplier tubes. The position of a scintillation event within the crystal array is determined more accurately by selectively painting the side surfaces of the array crystals.
