COLLISION PREVENTION SYSTEM FOR STEREOTACTIC RADIATION THERAPY DEVICE

摘要

Disclosed is a collision prevention system for a stereotactic radiation therapy device. The collision prevention system for a stereotactic radiation therapy device according to the present invention, the radiation therapy device being used for radiosurgery or stereotactic radiation therapy and having a robot head moving around a patient's body and a radiation generation device mounted to the robot head, comprises: a distance detection sensor which is installed on the outer side surface of the robot head and detects a distance to a patient so as to generate approach distance information; and a control unit for controlling a movement of the robot head so as to prevent the robot head from colliding with the patient, according to the approach distance information received from the distance detection sensor. According to the present invention, a distance detection sensor is installed in a robot head moving around a patient, and a movement of the robot head is controlled by a control unit while a distance to the patient is detected by the distance detection sensor. Accordingly, the present invention can provide a collision prevention system that can check in real time the distance between a patient and the robot head approaching the patient, and can effectively prevent the robot head from coming into contact with or applying an impact to the patient.
