The use of time-of-flight (TOF) information in positron emission tomography (PET) significantly improves image quality. Commercially available TOF-PET systems currently have a coincidence resolving time (CRT) of ~500 ps FWHM. The TOF benefit is inversely proportional to the CRT. In recent years, several groups have achieved experimental CRTs of about ~100 ps FWHM at the bench-top level, using...

We present the requirements, challenges and possible implementations of the frontend electronics and the data acquisition systems for high-performance PET systems based on silicon photosensors. Two use cases, namely the APD-based breast scanner ClearPEM and the SiPM-based detector of EndoTOFPET-US, are used as illustrations. The application to a large sensitivity whole-body scanner with long...

The TOFPET is a low power, low noise SiPM readout ASIC targeted, but not limited to, Time-of-Flight applications. It consists of a 64-channel analogue block, calibration circuitry, golden-references, bias generators and a global controller, featuring all-LVDS digital interface. It integrates signal conditioning and discrimination circuitry and high-performance TDCs for each of its 64...

Important goals in clinical medical imaging are early disease detection, disease staging and ability to establish treatment efficacy; they all require the ability to reliably detect small changes in the appropriate biomarker distribution. High
imaging resolution and sensitivity and accurate data quantification are important elements, but so is the use of appropriate tracers and image...

Silicon photo-multipliers (SiPM) are novel type of photo-detectors whose success is growing in various scientific fields. They are compact devices composed of a few thousands of tiny avalanche photo-diode pixels grown on a common silicon substrate. The diodes are operated in Geiger mode so that any single carrier, generated either by photons or thermally in the depletion region, might trigger...
