Abstract
A particle beam irradiation apparatus includes a beam scanning indication unit which two-dimensionally indicates a position of a particle beam in series for each of slices obtained by dividing an affected area to be irradiated in an axial direction of the particle beam, a beam scanning unit which two-dimensionally scans the particle beam based on an indication signal from the beam scanning indication unit, a phosphor film which is provided between the beam scanning unit and a patient and emits light in an amount corresponding to a particle dose of the particle beam transmitting therethrough, an imaging unit which images the phosphor film for each of the slices, and a display unit which obtains an irradiation dose distribution of each of the slices from image data imaged by the imaging unit and displays the obtained irradiation dose distribution associated with a scanning position of the particle beam.
