Emergency stop device for proton therapy patient positioning device and emergency stop control method

Abstract

The invention discloses an emergency stop control method for a proton therapy patient positioning device. The method includes obtaining alarm information of a dangerous area in a patient positioning process, confirming whether a person enters the dangerous area of the treatment room according to the obtained alarm information of the dangerous area in the positioning process of the patient, the control unit determines whether or not a person enters the dangerous area based on the acquired information, when it is confirmed that a person has entered the dangerous area of the treatment room, controlling the patient positioning device to stop running, when it is determined that a person has entered a hazardous area, the control unit abruptly stopping the patient positioning device in the treatment room, when a signal is detected that may pose a threat to the safety of personnel, the operation of the positioning device can timely stopped, on the one hand, can avoid the injury of the personnel caused by the mechanical collision, on the other hand, can avoid the harm that the personnel are in the radiation area and irradiated by the radiation in the working process of the image system. Theinvention can improve the safety protection effect in the treatment room and avoid the safety accident in the treatment room.

Description

technical field [0001] The invention belongs to the technical field of personnel safety protection in the medical industry, and relates to an emergency stop control technology for patient positioning equipment, in particular to an emergency stop device and emergency stop control method for proton therapy patient positioning equipment. Background technique [0002] Proton radiation therapy is one of many radiation treatments. It is not only a product of the historical development of radiation therapy, but also a product of the development of proton therapy itself. The advanced technologies used in current proton therapy, such as stereotaxic, radiographic, intensity-modulated radiotherapy, etc. All stem from the needs of radiation therapy itself. [0003] The patient positioning equipment for proton therapy mainly includes a treatment bed, a rotating frame and an imaging system. After the patient is positioned, the proton beam therapy is performed. Due to the mechanical movem...

AI Technical Summary

Problems solved by technology

Due to the mechanical movement of the treatment bed and rotating frame involved in the patient positioning process, it may pose a threat to the safety of personnel. At the same time, during the operation of the imaging system, X-ray radiation will be generated, which will have adverse consequences for the personnel present. , in order to solve the above defects, a solution is now provided
