Abstract
Provided is a charged particle irradiation apparatus that performs scanning with a charged particle beam and irradiates an irradiation target spot by spot. An embodiment of the present invention provides a charged particle irradiation apparatus () including: a first dose monitor () mounted in an irradiation nozzle (); an irradiation pattern converting device () that generates irradiation control data used for controlling the charged particle irradiation apparatus () from treatment plan data including information on a dose rate and a dose of a charged particle beam for each spot; and a dose correction factor storage unit () that stores data of a dose correction factor with respect to a dose rate of a charged particle beam. The irradiation pattern converting device () is configured to select one spot in the treatment plan data, for instance.
