Next generation PET scanners should fulfill very high requirements in terms of spatial, energy and timing resolution. Modern scanner performances are inherently limited by the use of standard photomultiplier tubes. The use of Silicon Photomultiplier (SiPM) matrices is proposed for the construction of a 4D PET module based on LYSO continuous crystals, which is envisaged to replace the standard PET...
Monte Carlo simulations were carried out in order to evaluate the performance of readout solutions for monolithic LYSO blocks, considering several 2D array configurations of discrete SiPMs. Results were compared to conventional multianode PMT readout. Our findings show that a detector module based on an array of 8×8 discrete SiPM may lead to better energy resolution and comparable spatial resolution...
An eight-channel readout ASIC has been developed for reading out signals from Silicon Photomultiplier (SiPM) for PET applications. It converts both signal charge and occurring time to digital timing pulses and only needs TDC. It has the advantages of simplified circuit design, reduced power consumption and suitable for large number of readout channels. The ASIC uses a fully current mode preamplifier...
We designed and built a data acquisition module based on the NOVA RENA-3 ASIC that is suitable for readout of multiple detector types, including APDs, PSAPDs, CZT, CdTe, and Si. The module was designed as a repeatable component for a 1 mm3 resolution breast-dedicated PET system that employs LYSO-PSAPD detectors. The PET system is made of 2 panels, each containing 2304 PSAPDs in a 16 cm × 9 cm × 2...
