Abstract

We have designed and developed a complementary metal-oxide-semiconductor (CMOS) solid-state photomultiplier (SSPM). We have studied this novel SSPM as a readout of LYSO scintillator for use in positron emission tomography (PET). Here we present energy resolution, coincidence timing resolution, depth of interaction measurements and flood imaging studies with SSPMs coupled to LYSO scintilators. Two different sizes, 3×3 mm2 and 1.5×1.5 mm2 SSPMs were studied. The measured FWHM energy resolution with 511 keV gamma rays was 22% for the detector consisting 3×3 mm2 SSPM coupled to a 3×3×15 mm3 LYSO and 11.2 % for the detector consisting 1.5×1.5 mm2 SSPM coupled to 1.5×1.5×10 mm3 LYSO. The timing resolution measured was 1.8 ns for the 3×3 mm2 detector in coincidence with a detector consisting LSO coupled to PMT. The coincidence timing resolution was 530 ps for 1.5×1.5 mm 2 detector. The measured depth-of-interaction resolution by coupling two 1.5×1.5 mm2 SSPMs on opposite ends of a 1.5×1.5×20 mm3 LYSO scintillator was 2.5 mm. The flood histogram was recorded with a 4×4 LYSO array, each element measuring 1.5×1.5×15 mm3 coupled to a position sensitive SSPM (PS-SSPM) consist of a 4×4 array of SSPM elements. The flood image was distortion free, all 16 elements were clearly visible and well separated from each other.
