Timing resolution and energy resolution of the dPET system. a NEMA NU2-2018 timing resolution in FWHM and FWTM as a function of activity concentration. b Stability of timing resolution (22Na point source based) within the 31-month monitoring time window. It demonstrates a slight improvement from 325 ps to 322 ps when system calibration was performed 6 months after installation. c Stability of energy resolution during the monitoring time period
