106. Time of flight: the last frontier in PET

Georgios Konstantinou (EPFL)

PET, through recent advancements comes close to the absolute limits of its potential. Spatial resolution matches the positron range; TB PET offers as good as complete coverage of the subject; machine learning-driven algorithms make the most out of each coincidence. ToF, in contrast, remains away from its own limit. Clinical state of the art is down to 178 ps with Siemens Biograph Vision X,...

Fast timing

Oral

In recent years, Fondazione Bruno Kessler (FBK) in Trento, Italy, has been actively involved in the development of several Silicon Photomultiplier (SiPM) technologies, particularly for applications such as time of flight-positron emission tomography (TOF-PET) where a fast timing is crucial. This work presents FBK's latest development, the Near-Ultraviolet Deep-junction (NUV-DJ) SiPM...

A new PETsys ASIC in the TOFPET series, named TOFPET3, has been developed aiming at high performance PET applications. The new chip has a 64-channel analog front-end with baseline stabilization, pulse tail cancelation, dark noise rejection and gain configuration. In each channel, three 10-bit digitization of pulses above a configurable threshold are performed (2 TDC, 1 QDC). The maximum event...

72. Second Generation Readout Electronics Design for a PET Detector That Achieves ~100 ps CTR and <2 mm DOI Resolution

Fast timing

Oral

This study introduces second-generation front-end electronics design for side-readout detectors, with the ultimate goal of realizing near 100 ps CTR Time-of-Flight 3D Position Sensitive (TOF-3DPS) detectors. Leveraging a previously proposed timing signal multiplexing scheme based on RF amplifiers and summing circuits, this design utilizes complex programmable logic devices (CPLDs) and discrete...

31. Fast Detectors Viewed from a Different Angle: Scintillators and SiPMs for Photon-Counting CT

Fast timing

Oral

Photon-counting computed tomography (PCCT) is a rapidly emerging medical imaging technology. Several PCCT scanners were recently developed based on finely pixelated room-temperature semiconductor detectors. Although scintillation detectors were traditionally considered too slow to handle the X-ray fluence rates > 108 photons s-1 mm-2 encountered in PCCT, the fast signals provided by modern...
