description Increased accuracy of proton beam delivery provides additional benefits to the patients undergo the treatment. A prompt gamma imaging detector can provide additional information during the treatment, as the prompt gammas produced by the interactions between protons and human tissues are related to the range and profile of the beam in the patient. This paper makes a Monte Carlo feasibility study for a pixelated prompt gamma imaging detector which can not only measure the proton range but also merge the beam profile and 3D beam image inside the patient. FLUKA simulation result shows that this detector can reduce background noise and measure the range and beam profile by using of grated shielding material, vertical gammas selection and a 5 MeV energy window.
