dc.description.abstract | We have evaluated the coincidence time resolution (CTR) performance of four different mixed-signal front-end electronic readout configurations with the goal to achieve 100 picoseconds (ps) CTR. The proposed TOF-PET detector elements are based on two 3x3x10 mm(3) "fast LGSO" crystal segments, side coupled to linear arrays of 3x3 mm(2) silicon photomultipliers (SiPMs), to form a total crystal length of 20 mm. We studied multiple configurations and components for the front-end readout: 1) high speed radio frequency (RF) amplifiers; 2) an ASIC-based discriminator; 3) a combination of RF amplifier, balun transformer, and discriminator ASIC; and 4) combination of balun transformer and discriminator ASIC. Using two 3x3x10 mm(3) fast LGSO crystals side coupled to a linear array of three SiPMs, coincidence data were experimentally acquired for each readout configuration in combination with a low jitter field-programmable gate array (FPGA)-based time-to-digital converter (TDC). After evaluating the timing performance of the three readout schemes, the best CTR value of 99.4 +/- 1.9 ps FWHM was achieved for configuration (3), which is more than 20 ps better than the results achieved using configurations (1), (2), and (4). | - |
