DEVICE FOR CONTROLLING RADIATION THERAPY DEVICE, RADIATION THERAPY SYSTEM, METHOD FOR CONTROLLING RADIATION THERAPY DEVICE, AND PROGRAM

摘要

This device for controlling a radiation treatment device is provided with a gantry for supporting a radiation emitting device so as to enable rotation thereof about a first axis, and a ring for supporting the gantry so as to enable rotation thereof about a second axis intersecting with the first axis, the device for controlling a radiation treatment device being provided with a movement path information storage unit for storing movement path information set in the radiation emitting device, and a control unit for providing a limit to the rotation speed of the gantry and the rotation speed of the ring while maintaining the ratio of the rotation speed of the gantry and the rotation speed of the ring indicated by the movement path information, on the basis of the rotation angle of the gantry and the rotation angle of the ring.

主权项

1. A device for controlling a radiation therapy device which includes a gantry by which an irradiation device is supported in such a way as to be able to rotate around a first axial line, and a ring by which the gantry is supported in such a way as to be able to rotate around a second axial line intersecting with the first axial line, the device comprising:
a movement path information storage unit configured to store information regarding a movement path set for the irradiation device; and a control unit configured to set a limitation to the rotational speeds of the gantry and the ring while maintaining the ratio between the rotational speed of the gantry and the ring, which is indicated by the information regarding the movement path, based on the rotational angles of the gantry and the ring.
