摘要： The particle beam irradiation apparatus according to the present invention comprises: a beam generation unit; a beam emission control unit which controls emission of the particle beam; a beam scanning indication unit which two-dimensionally indicates a position of the 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 slice; and a display unit which obtains an irradiation dose distribution of each slice from image data imaged by the imaging unit and displays the obtained irradiation dose distribution associated with a scanning position of the particle beam.
