Abstract: Disclosed are a radiotherapy assistant apparatus for modulating a build-up region of a photon beam for a radiotherapy, a radiotherapy system including the radiotherapy assistant apparatus, and method for the radiotherapy system. The radiotherapy assistant apparatus for modulating a build-up region of a photon beam for a radiotherapy, including at least: a magnetic field generator that generates a magnetic field that has a direction perpendicular to a movement direction of the photon beam, the magnetic field generator is disposed on a movement route along which the photon beam moves toward a target portion of the radiotherapy; and a magnetic field intensity adjuster that adjusts an intensity of the magnetic field generated by the magnetic field generator. The magnetic field generator disperses secondary electrons that have particular energy levels equal to or lower than a preset value.
