摘要： PROBLEM TO BE SOLVED: To prevent the motor trip of a driving device which moves an irradiation device for applying therapeutic radiation, and to highly accurately move the irradiation device. SOLUTION: The radiotherapy apparatus controller includes: an irradiation object detection part for calculating a target position 131 on the basis of a specified part position at which a specified part is arranged inside a subject; and a swing position control part for controlling the driving device which moves the irradiation device so that the irradiation device which applies the therapeutic radiation is turned to a corrected target position 132. The corrected target position 132 indicates a position closer to a position to which the irradiation device 16 is turned than to the target position 131 in a preparation period 96 before a treatment period, and indicates the target position 131 during the treatment period 97.

摘要： PROBLEM TO BE SOLVED: To operate a radiation apparatus exposing a therapeutic radiation with higher accuracy.
SOLUTION: An operation method involves a step of computing a predicted path 73 based on affected part positions from 71-0 to 71-n where the affected part is disposed for measuring time from t
0 to t
n , a step of computing a control path 75 based on the predicted path 73, a step of controlling a driving device for driving a radiation apparatus to put the radiation apparatus toward the control path 75, and a step of controlling the radiation apparatus to expose the therapeutic radiation only when the difference between the position of putting the radiation apparatus and the predicted path 73 is within a predetermined error range. The operation like this can drive the radiation apparatus with higher accuracy to make the period for exposing the therapeutic radiation to the affected part much longer.
