A high resolution positron emission tomograph (PET) for brain studies has been developed, which consists of 5 detector rings (240 BGO's/ring). New multi-segment photomultiplier tubes (PMT) were adopted to the system with 5 mm wide BGO's. The system is designed to examine a patient sitting or lying down on a chair/bed couch. The functions of PMT auto gain control and real time image display are implemented in the system. The physical performance of the system was evaluated: the spatial resolution is 3.5 mm in the transaxial plane and 5.7 mm in the axial direction, and the total system sensitivity is 109 kcps/{mu}Ci/ml for a 20 cm dia. uniform phantom with a pulse height threshold of 350 keV.
