“…The ER of 17.5% at 511 keV and the CTR of 357 ps (FWHM) were demonstrated. Since then, significant progress had been made in EQR SiPM technology, a peak PDE of 34% for 420 nm photons and an intrinsic single photon timing resolution (SPTR) of 81 ps at 9 V over-voltage were obtained for the promoted EQR SiPM having a 3 × 3 mm 2 active area and comprising 90000 individual cells [10]. In this report, we present the latest progress of EQR SiPM on PET applications, and verify that it can be a promising readout detector for PET imaging.…”
