Sensor network architecture for a fully digital and scalable SPAD based PET system

Digital SiPMs in the recent past have emerged as a viable low cost alternative to PMTs providing higher granularity and MRI compatibility. The rich dataset generated by digital SiPM sensors have posed a challenge, especially at the system level when a multitude of such sensors are to be used. In this paper we present a sensor network based approach for data acquisition, scalable to multi-ring based pre-clinical, clinical and brain PET.
