Title: Design considerations of an animal PET scanner utilizing LSO scintillators and position sensitive PMTs
Conference Title: 1994 IEEE Nuclear Science Symposium
Abstract: Various parameters relevant to the design of a small scale PET scanner were studied both experimentally and by computer simulation. LSO (cerium-doped lutetium oxyorthosilicate) was compared with BGO, using a position sensitive PMT (PSPMT). (Compared to BGO, LSO has 8 times faster decay time, 4 times the scintillation light output, but 14% lower attenuation coefficient for 511 keV photons). The experiments with BGO and LSO involved: the crystal identification on the face of a PSPMT, measurement of the coincidence line-spread functions, and measurement of the sensitivity above the electronic noise. The resulting coincidence images clearly resolved each LSO crystal. EGS4 Monte Carlo simulations were used to estimate the efficiency, singles rate and mispositioning due to the depth of interaction for PET scanners with various sizes of LSO and BGO.
