SensL’s Matrix products provide a modular, turnkey readout system specifically designed for nuclear medicine applications. Building on SensL’s silicon photomultiplier technology, the MatrixB provides a fully solid-state, four-side scalable sensor for the readout of L(Y)SO or BGO scintillator arrays. It integrates all of the electronics required to localize, time stamp and discriminate scintillation events. Digitized event data comprising time, location and energy are sent to the host system via a high-speed USB interface. Integrating multiple sensor arrays, the system can perform temporal coincidence analysis thereby reducing data rates and the computational load on the host system.
