In SPADnet we have advocated the use of standardized photonic modules for modular assembly of PET systems. In this paper, we tackle the scalability problem, starting from synchronization. Since the photonic modules in a ring must ensure tens of picoseconds in timing accuracy, it is essential that the synchronization of each module be accurate, irrespective of the number of modules in a ring, the ring's...
The design and realization of a truly scalable, distributed real time coincidence detection technique for multi-ring based Positron Emission Tomography (PET) systems is presented in this work. To ensure scalability to various PET configurations, the design was optimized at two abstraction levels. First, at the system level, a network was designed to facilitate lower packet latency. Second, at the...
