We have previously reported that a brain PET using GAPD arrays was successfully developed. The brain PET consisted of 72 4 × 4 GAPD arrays combined with LYSO crystals (single pixel size: 3 mm × 3 mm). Each 4 GAPD arrays' output signals were sent to a 64:1 position decoder circuit (PDC) which detects the fastest gamma signal of 64 input channels. To further improve the PET system performance, several...
The development and assessment of a readout system based on Field Programmable Gate Array (FPGA) for dedicated nuclear medicine cameras is presented. We have used Xilinx Spartan3e, which is one of the simplest FPGA evaluation boards. The aim of this work is to offer a simple, opensource data acquisition tool, which provides accurate results for nuclear imaging applications.. The system has been evaluated...
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...
The forward silicon vertex tracker (FVTX) is a silicon detector being planned as an upgrade to the PHENIX experiment at RHIC. Four layers of silicon strip layers at forward and backward rapidity will add to the vertex capability of the PHENIX silicon vertex tracker (VTX) enabling measurement of secondary vertices in front of the PHENIX muon arms. This allows the identification of heavy-quark decays...
PANDA is a new universal detector for antiproton physics at the HESR facility at FAIR/GSI. The PANDA data acquisition system has to handle interaction rates of the order of 10**7 /s and data rates of several 100 Gb Is. FPGA based compute nodes with multi-Gbit/s bandwidth capability using the ATCA architecture are designed to handle tasks such as event building, feature extraction and high level trigger...
