The spatial resolution performance characteristics of a monolithic crystal PET detector utilizing a sensor on the entrance surface (SES) design is reported. To facilitate this design, we propose to utilize a 2D silicon photomultiplier (SiPM) array device. Using a multi-step simulation process, we investigated the performance of a monolithic crystal PET detector with different data readout schemes...
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...
Detection and spectroscopic tests of three self-triggered silicon detection modules constructed using Tape Automated Bonding and micro-cable technologies and equipped by VATA read-out chips are presented and compared. Results of these tests are demonstrated using hit maps and pulse-height spectra induced by 133Ba, 241Am, and 57Co radioactive sources of X- and gamma rays. We have observed significant...
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...
