"WebOct 10, 2024 · A gamma photon that scatters within the patient will never hit the scintillator with the full energy (i.e. it won’t lie within the peak). Therefore, only gamma photons in the peak can be confidently identified as non-scattered radiation from the patient. Usually a 20% acceptance window is used centred on the photopeak.
