  • Distributed coincidence processor
    Patent number: 6828564
    Abstract: A PET scanner includes a first module processor for detecting a first event occurring at a first detector module and a plurality of remaining module processors, each of which is configured for detecting a second event occurring at a corresponding remaining detector module. The plurality of remaining module processors is divided into first and second subsets. The module processors in the first subset are configured to receive, from the first module processor, a first signal indicating an occurrence of the first event. The module processors in the second subset are configured to provide, to the first module processor, a second signal indicating an occurrence of the second event.
