Innovative Electronics Architecture for PET Imaging

The INNOTEP collaboration investigates for a technological adaptation of high energy physics (HEP) detection and acquisition concepts to the PET issues. We present preliminary results of innovative electronics architecture for PET. The concept is based on a deadtimeless pipelined processing of the photosensors signals. After shaping and sampling by a free-running ADC, the pulses are digitally filtered to extract time and energy. The data is processed and selected inline before storage. We present the first tests of the low noise front-end electronics - preamplifier, shaper, ADC - and a time of flight-capable digital filtering technique.
