Claim One:
1. A radiotherapy system, comprising: a radiotherapy apparatus; and a radiotherapy apparatus control apparatus, wherein the radiotherapy apparatus comprises: a radiation irradiation unit that irradiates a therapeutic radiation; and a driving unit that changes positions of the radiation irradiation unit, wherein the radio therapy apparatus control apparatus comprises: a selecting section configured to select a plurality of template transmission images from a plurality of transmission images imaged by using radiation transmitting through a specimen; a template generating section configured to generate a template set including a plurality of templates based on the selected template transmission images; a matching degree calculating section configured to calculate a plurality of matching degrees based on each template of the template set and the plurality of transmission images; a display section; an imaging section configured to image a location measurement transmission image from the radiation transmitting through said specimen; a template matching section configured to perform pattern-matching of each template of said template set with said location measurement transmission image and select an optimal template which is the most similar to a portion of the location measurement transmission image, from said template set; a location calculating section configured to calculate a location of a specific site of said specimen based on said location measurement transmission image and said optimal template; a control unit configured to control the driving unit to drive the radiation irradiating unit to a position where the radiation irradiation unit irradiates the therapeutic radiation through said specific site location; and an irradiating section configured to control said radiation irradiating unit to irradiate the therapeutic radiation through the specific site location, wherein said display section displays a display image on a display unit including the plurality of transmission images which are classified on the display unit based on the plurality of matching degrees, wherein said selecting section selects, in response to an instruction by a user, a template transmission image from the plurality of transmission images which are classified on the display unit based on the plurality of matching degrees, wherein the template generating section adds a new template based on the selected template transmission image and modifies the template set, wherein each of the plurality of matching degrees indicates a similarity between a portion of a corresponding one of said plurality of transmission images and one template of said template set, and wherein said display image includes a first region and a second region, wherein first transmission images of said plurality of transmission images from which the matching degrees higher than a predetermined threshold have been calculated are displayed in the first region, and wherein second transmission images of said plurality of transmission images from which the matching degrees lower than the predetermined threshold have been calculated are displayed in the second region.
