Abstract：
Position sensitive photomultiplier tube (PS-PMT) represents a technological improvement in the development of new concept gamma cameras based on the principle of a single tube. Very recently, a new compact PS-PMT, Hamamatsu R7600-C12, has been developed. The PS-PMT has 11 stages of metal channel dynodes and 6(x)+6(y) crossed plate anodes in a 25.7mm square ×20mm high metal can package, where the effective area is 22×22mm 2. Tests of spatial resolution, spatial linearity, gain uniformity and timing resolution were carried out by coupling the PS-PMT to the LSO an GSO scintillators in terms of applicability to Positron Emission Tomography (PET) system. High spatial resolution of about 1.4mm is obtained by using LSO crystals coupled to the PS-PMT, and the good spatial linearity, gain uniformity and timing resolution are also obtained.
