Title:
CONTROL DEVICE AND METHOD FOR ROTATION OF RADIOTHERAPY EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2017/071451
Kind Code:
A1
Abstract:
A control device (100, 200) and method for rotation of radiotherapy equipment. The control device (100, 200) is used for controlling synchronous or asynchronous rotation of all rotating loads (110, 210) of the radiotherapy equipment around a rotation axis; the control device (100, 200) and the radiotherapy equipment form a full closed-loop structure; the control device (100, 200) comprises: a monitoring module (120, 220) used for monitoring all the rotating loads (110, 210) of the radiotherapy equipment and recording offset when rotation offset occurs; a control module (130, 230) used for generating, according to the offset, a correction instruction for correcting offset when the monitoring module (120, 220) detects the offset of at least one of the rotating loads (110, 210) of the radiotherapy equipment; and a driving module (140, 240) used for driving all the rotating loads (110, 210) of the radiotherapy equipment to rotate around the rotation axis and, according to the correction instruction sent by the control module (130, 230), driving a rotation load (110, 210) having offset to move to correct the offset. By means of monitoring the real rotation condition of rotation loads (110, 210) of the radiotherapy equipment, the said control device (100, 200) and method make timely correction when a rotation offset occurs, thereby improving security and positioning accuracy of the radiotherapy equipment.
