Abstract

Positron emission tomography is a highly sensitive molecular imaging modality, based on the coincident detection of annihilation photons after positron decay. The most used detector is based on dense, fast, and luminous scintillators read out by light sensors. This review covers the various detector concepts for clinical and preclinical systems.

Keywords: Avalanche photodiode; PET detectors; Photomultiplier tubes; Positron emission tomography (PET); Silicon photomultiplier.
