Abstract：
We are developing a high specificity detector for detecting the increased metabolic rate of breast tumors. Positron emission mammography (PEM) provides a highly efficient, high spatial resolution positron imaging system. PMT plays a very important role in PEM detectors, because most of the systems consist of scintillator arrays coupled with PMT. Our detector is composed of 20×20 arrays of 2mm×2mm×20mm of Bi₄Ge₃O₁₂ (BGO) scintillators and a novel flat panel position-sensitive PMT (FP-PS-PMT) -Hamamatsu R8400-00-M256. Spatial resolutions of 2.0mm FWHM and energy resolutions of 23% FWHM are achieved.
