SiPM based detector module and digital data acquisition system for PET: Initial results

Abstract: Abstract-A novel detector module configuration based on silicon photomultiplier (SiPM) detectors with LYSO scintillators, a multichannel mixed analog/digital ASIC and an FPGA-based digital data acquisition system has been developed for preclinical positron emission tomography (PET). The SCEPTER ASIC, originally developed for soft X-ray detection at Brookhaven National Laboratory, has a unique architecture incorporating multiple peak detectors and time-to-amplitude converters, and offers an extremely low dead t… Show more

“…The SPMM-3035 shows better energy resolution, which ranges from ∼40% for BGO with 22 Na irradiation to 11% for LYSO:Ce and 137 Cs excitation. The energy resolution of SPMM-3035 with LYSO:Ce and 22 Na at 29 V and 30 V was found equal to 20% and 15%, respectively, which is in good agreement with the literature [19,20]. SiPM-3035, which has larger cells, provides better energy resolution, as has also been demonstrated by other groups [12,20].…”

“…Generally, a larger number of microcells per photosensor yields a wider dynamic range and increases the linearity of the detector response. However, due to the fine gaps between microcells, increasing the number of microcells decreases the fill factor, thereby reducing the sensor's detection efficiency [1,15,19,20].…”

“…Each detector module consists of a 4x4 array of 3 mm 2 silicon photomultiplier (SiPM) detectors, each optically coupled to a 3 mm 3 LYSO scintillator. The detector mod ules are interfaced to a multichannel mixed analog/digital ASIC and an FPGA-based digital data acquisition (DDAQ) system [7]. The ASIC, originally developed for soft X-ray detection at Brookhaven National Laboratory, is based on a unique architecture incorporating multiple peak detectors and time-to-amplitude converters, and offers an extremely low dead time, making it ideal for application to PET signal acquisition [8].…”
