Abstract
A radiotherapy apparatus controller includes: an imperfect three-dimensional data calculating unit configured to calculate an imperfect three-dimensional data based on a plurality of imperfect transmission images which is respectively imaged from a plurality of imperfect directions except a predetermined direction among a plurality of directions different from each other; an imaging unit configured to image an additional transmission image from the predetermined direction by using an imager system; a perfect three-dimensional data calculating unit configured to calculate a perfect three-dimensional data based on the additional transmission image and the imperfect three-dimensional data; and a position calculating unit configured to calculate a position of a part of a subject inside based on the perfect three-dimensional data. The radiotherapy apparatus controller can faster calculate the position with higher precision.
