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.

REAL LIFE EXAMPLES
A mini-PET detection system for teaching and studying: Using one BDM PET detector module and a normal computer system, you can set up a mini-system for PET coincidence detection and imaging. Such systems provide you the original event pulse from the detector in digital waveform. You can use it to study and teach the PET detection process and principle.
A PET system for imaging: With several BDM | PET Detector Modules and a high-performance computer system, you can quickly setup a PET system.
