摘要：A radiation therapy apparatus control method includes: calculating a plurality of degrees of similarity corresponding to a plurality of matching target areas based on a radiographic image; calculating a specific image position where a specific image area corresponding to a maximum value of the degrees of similarity out of the matching target areas is positioned in the radiographic image; and calculating a drive amount with which a therapeutic radiation ray irradiation device is driven, based on the specific image position. The operation of calculating the one degree of similarity corresponding to the one matching target region out of the degrees of similarity includes: referring to a template table in which the plurality of matching target areas are associated with a plurality of sets of templates to calculate a set of templates corresponding to the one matching target area out of the plurality of sets of templates; and detecting, from the set of templates, a similar template most similar to a matching target image displayed in the one matching target area of the radiographic image.
