A BSTRACT : The distribution of the prompt gamma emissions induced by proton interactions in a target material carries information concerning the proton range and target composition. We propose multiple approaches for prompt gamma imaging depending on the quantity of interest and the detection scenario. The first approach is a practical design based on knife-edge collimator utilized in tandem with a compact PET type detector to verify range by measuring depth distribution of prompt gamma in an…

Characterization of Single-Photon Time Resolution: From Single SPAD to Silicon Photomultiplier
In this paper, we report on the characterization of the single-photon time resolution (SPTR) of the RGB (Red-Green-Blue) type silicon photomultipliers (SiPM) produced at FBK. We measured and compared
3D prompt gamma imaging for proton beam range verification
TLDR
3D PG imaging for proton range verification under clinical beam delivery conditions is possible with a single Compton camera, and shifts in the proton beam range as small as 2 mm could be detected for delivery of a 2 Gy spot.

TLDR
The focus of this review is on timing performance and it appears feasible to improve the coincidence resolving time from the values achieved by current state-of-the-art TOF-PET systems to about 100 ps or less, even though this may require the implementation of advanced methods such as time resolution recovery.
