The evolution of positron emission tomography cameras towards continuous sampling of individual position-sensitive photomultiplier anodes with processing algorithms implemented on digital programmable logic devices creates a new framework where new approaches to the γ-event detection are possible. We have developed a system model of the acquisition chain, including multi-layer phoswich, photomultiplier, front-end analog electronics, data acquisition and data processing. This processing includes estimation algorithms for the most relevant event parameters: energy, layerof- interaction, time picking-off and event location. The selected simulation platform couples gently to digital hardware simulation tools, in such a way that implemented models may generate reallike stimuli for the digital system under development. The modeling of the whole front-end electronics enables deeper understanding and tuning of different system trade-offs and provides a rapid and soft transition between specification and hardware development.application/pdfeng© IEEEContinuous samplingDepth of interactionFrontend electronicsNuclear pulse processingHardware validationPositron Emission Tomography (PET) Modelingconference paperBiología y Biomedicina10.1109/NSSMIC.2004.1466334open access308930932004 IEEE Nuclear Science Symposium Conference Record5
