摘要
Obtaining images with high resolution and contrast from short exams is crucial for the viability of Positron Emission Mammography as an early breast cancer detection technique. The Clear-PEM detector is a Positron Emission Mammography scanner, developed by the Portuguese Consortium in the framework of the Crystal Clear Collaboration at CERN, based on high-granularity avalanche photodiodes readout with 12288 channels, coupled to pixilated 2x2x20 mm(3) LYSO:Ce crystals in a double readout configuration. The scanner features a high bandwidth three-level acquisition system with negligible dead time in order to minimize exam time. The frontend is instrumented with low-noise amplifier/discriminator/multiplexer ASICs (L0 trigger) and free-running ADCs while the off-ddetector electronics, implemented in FPGAs, computes the trigger primitives from the pulse amplitude and timing. With this information the readout electronics selects interesting photoelectric events and groups multi-hit events due to in-Compton scatter into possible coincidences. After a first-level trigger (L1) is generated, filtered data is read out over a high speed data link into a second-level (L2) software trigger which reprocesses the selected events in temporal coincidence with more accurate energy and time extraction algorithms. The DOI coordinate and the re-validated energy and time allow to achieve an improved reconstruction of in-detector Compton scattering and rejection of random and scattered coincidences. On this paper, we report on the experimental validation, characterization and optimization of the L1 data acquisition electronics, readout link and L2 software trigger and present performance results. We discuss the validation of the associated operation software.
