Photon beam code of practice
WebApr 14, 2024 · For example, external beam radiation therapies (EBRTs) that use photon beams are used to treat head and neck cancer while EBRTs that use electron beams are used for superficial cancers such as cutaneous T-cell lymphoma, also known as mycosis fungoides, which requires total skin electron irradiation . Electron therapy has been used … WebNeutron therapy beams are obtained by accelerating protons or deuterons on Beryllium. These neutron therapy beams present comparable dosimetric characteristics as those for photon beams obtained with linear accelerators; for instance, the penetration of a p(65)+Be neutron beam is comparable with the penetration of an 8 MV photon beam.
