Abstract :
We report on a distributed online coincidence detection implementation that we have recently added to the miniPET-II small animal PET scanner. The implementation uses standard Ethernet and IP multicasting techniques, therefore no architectural changes were necessary to the existing system. For 2D reconstruction the implementation scales with the number of detectors in the system, so it can be used for larger ring configurations, too. The online coincidence detection makes the system suitable for real time imaging applications.
