Innovation in online hadrontherapy monitoring: An in-beam PET and prompt-gamma-timing combined device

Abstract

Quality assurance in particle therapy is an open issue that can be addressed with reliable monitoring techniques, such as in-beam PET and prompt-gamma-timing (PGT). In-beam PET is able to provide online feedback on the particle range by detecting the radiation related to the β+ activity, while PGT relies on the time-of-flight (TOF) of prompt photons. The I3PET (In-beam PET Innovative Imaging) project is developing a novel scanner demonstrator that combines in-beam PET and PGT within the same detector, exploiting the potential synergy of these two techniques.
