A novel detector module configuration based on silicon photomultiplier (SiPM) detectors with LYSO scintillators, a multichannel mixed analog/digital ASIC and an FPGA-based digital data acquisition system has been developed for preclinical positron emission tomography (PET). The SCEPTER ASIC, originally developed for soft X-ray detection at Brookhaven National Laboratory, has a unique architecture...
A real-time stereo vision system, based on configurable logic boards, is described. Many reported stereo-matching systems are based on numerically intensive measures such as normalized cross-correlation which is expensive in terms of logic. Non-parametric measures require only simple, parallelizable, functions such as comparators, counters and exclusive-or, and are thus very well suited to FPGA implementation.
