摘要
A decreased number of readout method is investigated here to provide precise pixel information for small-animal positron emission tomography (PET). Small-animal PET consists of eight modules, each being composed of a 3 x 3 array of 2 mm x 2 mm x 20 mm lutetium yttrium orthosilicate (LYSO) crystals optically coupled to a 2 x 2 array of 3 mm x 3 mm silicon photomultipliers (SiPMs). The number of readout channels is reduced by one-quarter that of the conventional method by applying a simplified pixel-determination algorithm. The performances of the PET system and detector module were evaluated with experimental verifications. In the results, all pixels of the 3 x 3 LYSO array were decoded well, and the performances of the PET detector module were measured.
