Description	Prompt gamma (PG) imaging has become the most promising technique for real-time in vivo range verification in particle beam therapy. Since its initial proposal in 2003 by Stichelbaut and Jongen at the PTCOG meeting, several groups around the world have conceived and developed prototypes using a variety of Monte Carlo (MC) codes such GEANT4, FLUKA, MCNPX, GATE/GEANT4, TOPAS/GEANT4, etc. During proton or heavy ion therapy, primary particles from the treatment beam interact with elemental nuclei in the tissue, which can leave behind an intact nucleus in an excited state. This excited state quickly $(<10^{−9 }$s) decays by emitting characteristic PG. Since the PG emission only occurs in regions in which the treatment beam interacts in the tissue, the distribution of PG creation in the patient is correlated to the distribution of dose delivery to the patient. Also, since the excited nuclear states are quantized, each element emits a unique and characteristic PG spectrum. Thus, the spectral analysis of PG emitted from tissue may provide useful information about the elemental concentration, composition, and type of the tissues irradiated during treatment.
