摘要： A radiation tomography method of the present invention includes: calculating a radiating timing, with reference to imaging timing correction data relating a plurality of gantry angles to a plurality of imaging timing correction amounts, on the basis of an imaging timing at which a radiation source supported by a rotating traveling gantry is arranged at a predetermined imaging angle and an imaging timing correction amount, of the plurality of imaging timing correction amounts, related to a gantry angle at which the traveling gantry is arranged at the imaging timing; and calculating, on the basis of an X-ray image imaged with a radiation radiated from the radiation source at the radiating timing, three-dimensional data of the X-ray image of a subject. According to the radiation tomography method, the X-ray image imaged with the further accurately arranged radiation can be obtained even in a case where the traveling gantry deflects depending on the gantry angle at which the traveling gantry is arranged, and thus the three-dimensional data can be obtained more accurately.

摘要： A radiotherapy apparatus controller includes: a portal image taking unit; a gantry position collector; a marker position calculator; and a marker position table generator. The portal image taking unit takes a first transmission image, in which a marker member positioned at a predetermined position is shown, by using therapeutic radiation and an imager. The gantry position collector collects a first gantry position at which a gantry is positioned when the first transmission image is taken from a sensor measuring a position at which the gantry is positioned, the gantry supporting the imager and a therapeutic radiation radiating device which radiates the therapeutic radiation. The marker position calculator calculates a first marker position at which the marker member is shown in the first transmission image. The marker position table generator updates a marker position table, which correlates a plurality of gantry positions with a plurality of marker positions, so that the first gantry position corresponds to the first marker position.
