ANTI-COLLISION DETECTION METHOD AND DEVICE FOR RADIATION THERAPY MACHINE AND RADIATION THERAPY MACHINE

摘要

An anti-collision detection method for a radiotherapy machine, comprising: obtaining the contour of a patient in a treatment space (201); determining whether a target contour point exists on the contour, the distance between the target contour point and a moving object in the treatment space being less than a preset distance threshold (202); when the target contour point exists on the contour, triggering anti-collision interlocking (203). The described technical solution may reduce threats to the safety of a patient caused by a collision between the patient and a moving object in a treatment space. Further disclosed are an anti-collision detection device for a radiation therapy machine and a radiation therapy machine.
