Abstract
The present disclosure discloses a device for controlling rotation of a radiotherapy equipment, for controlling rotation of at least one rotational load of the radiotherapy equipment about a rotation axis. The device and the radiotherapy equipment form a full-closed-loop structure. The device includes: a detector, configured to detect the rotation of respective rotation axis in real time for each rotational load of the radiotherapy equipment during a treatment process, and record a rotational offset when the rotational load is rotationally deviated; a controller, configured to generate a correction instruction for eliminating the deviation according to the recorded offset when the detector detects at least one of the rotational loads of the radiotherapy equipment is deviated; and a driving apparatus, configured to drive each rotational load of the radiotherapy equipment to rotate about the rotation axis, and drive the deviated rotational load to move according to the correction instruction issued by the controller to eliminate the deviation.
