<P>PROBLEM TO BE SOLVED: To highly accurately expose radiations for treatment to the diseased part of a patient. <P>SOLUTION: The three-dimensional position P<SB POS="POST">i</SB>of the time t<SB POS="POST">i</SB>is calculated on the basis of the first predicted two-dimensional position Q<SB POS="POST">i-1</SB>of the time t<SB POS="POST">i-1</SB>, the first predicted two-dimensional position Q<SB POS="POST">i+1</SB>of the time t<SB POS="POST">i+1</SB>, and the second predicted two-dimensional position Q<SB POS="POST">i</SB>of the time t<SB POS="POST">i</SB>. The first predicted two-dimensional position Q<SB POS="POST">i-1</SB>and the second predicted two-dimensional position Q<SB POS="POST">i+1</SB>are predicted on the basis of a plurality of two-dimensional positions calculated from a plurality of first images imaged by a first imager. The second predicted two-dimensional position Q<SB POS="POST">i</SB>is predicted on the basis of the plurality of two-dimensional positions calculated from a plurality of second images. In such a radiotherapy apparatus control method, the three-dimensional position is more highly accurately predicted compared to the other method of calculating a measured three-dimensional position on the basis of the two two-dimensional positions calculated from the plurality of first images and one two-dimensional position calculated from the plurality of first images, and predicting a future three-dimensional position on the basis of the measured three-dimensional position. <P>COPYRIGHT: (C)2012,JPO&INPIT |
