Clear-PEM: A PET imaging system dedicated to breast cancer diagnostics
Abreu, M. C.; Aguiar, D.; Albuquerque, E.; Almeida, F. G.; Almeida, P.; Amaral, P.; Auffray, E.; Bento, P.; Bruyndonckx, P.; Bugalho, R.; Carriço, B.The Clear-PEM scanner for positron emission mammography under development is described. The detector is based on pixelized LYSO crystals optically coupled to avalanche photodiodes and readout by a fast low-noise electronic system. A dedicated digital trigger (TGR) and data acquisition (DAQ) system is used for on-line selection of coincidence events with high efficiency, large bandwidth and small dead-time. A sp...
