DexScanner E102 | Digital TOF PET Detector is a digital PET detector. It is optimized for TOF PET and high count-rate measurements. It is composed of LYSO (Lutetium Yttrium Orthosilicate), SiPM (silicon photo-multiplexer) and a scintillation pulse sampling circuit. The circuit conducts a MVT (multi-voltage threshold) method to sample the event pulse, yielding eight samples (depending on the number of the thresholds; here there are four) for a single pulse—four at the pulse’s leading edge and four at the pulse’s decay tail. The resulting samples are then streamed out via a standard Giga-bit Ethernet connector following the UDP (User Datagram Protocol). The time, energy and position information can be determined from the event samples. A SDK together with the data structure is provided to users for designing software to collect and analyze the event samples.
