N2 - The unique, circular topology of the QuickSilver electronics of the Siemens Inveon PET scanner distributes the coincidence event matching, as opposed to the traditional star structure with a centralized coincidence processor. This architecture provides a means to extend or integrate QuickSilver based systems without hardware modification. This paper reports on integrating a small, high-resolution PET insert, developed at Washington University (WU) in St. Louis, into a Siemens Inveon PET. The detectors in WU PET insert are equipped with LSO arrays coupled to Multi-Pixel Photon Counters (MPPC). Scintillation events detected by PET insert detectors are processed by a set of independent QuickSilver electronics. By placing this insert within the Inveon PET, one can achieve sub-millimeter resolution. By rerouting RocketIO (RIO, Xilinx standard) cables and modifying Field Programmable Gate Array (FPGA) firmware, the two PET systems can be integrated in such a manner as to create coincident pairs within the insert ring, within the original Inveon ring, and between the two rings.
