A method and apparatus for position detection, and a radiotherapy system are provided. The radiotherapy system includes: a treatment couch, a positioning apparatus, an optical tracking system and a computer; the positioning apparatus disposed on the treatment couch, and at least one reference point provided on the positioning apparatus; the optical tracking system disposed above the treatment couch and configured to detect relative positioning between a mark point set on a treated part of a patient and the reference point, determine deviation between the relative and reference positions, and send the deviation to the computer. The computer is configured to determine whether to adjust a position of the treatment couch based on the deviation and deviation range. The system provided by the present disclosure avoids the influence of patient movement on the accuracy of treatment, and prevents a treatment beam from damaging normal tissues of the patient.

Method and apparatus for detecting position, and radiotherapy system

A device and method for controlling the rotation of radiotherapy equipment are provided. The device includes: a detector, configured to detect the rotation of a rotational load of the radiotherapy equipment, and record a rotational deviation amount when the rotational load rotationally deviates; and a controller, configured to generate correction instructions for eliminating the deviation according to the rotational deviation amount when the detector detects the rotational load of the radiotherapy equipment rotationally deviates. The deviation occurred to the rotation of the rotational load is timely corrected by monitoring the actual rotation of the rotational load of the radiotherapy equipment, thereby improving the safety and positioning accuracy of the radiotherapy equipment.

Device and method for controlling rotation of radiotherapy equipment

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.
