Wireless induction type compensator interlocking device adaptive to externally-hung medical accelerator

Abstract

The invention provides a wireless induction type compensator interlocking device matched with a medical accelerator. The wireless induction type compensator interlocking device is composed of a machine connecting assembly and a compensator assembly. According to the method, the situation that manual checking and supervision are completely relied in the past is changed into accelerator automation and manual rechecking, the radiotherapy safety threshold value is greatly increased, and the working pressure of radiotherapy technicians is relieved; the implementation of the personalized compensator greatly reduces hospital infection, the adhesive compensator greatly improves the effect of attaching to the skin, and the design of the five-point electrode plate ensures that the compensator is tightly attached to the skin (a target area) in real time; the reduction of the gap between the compensator and the target region is beneficial to the uniform distribution of the dose in the target region. Function optimization is carried out on the premise that existing accelerator hardware is not changed, adaptability and generalization are higher, and normal maintenance of equipment is not affected. The method is reasonable in design, and potential loopholes in use of the compensator are solved. During use, the whole operation process is simple and feasible, and the device is suitable for clinical popularization and application of radiotherapy.

Description

technical field [0001] The invention belongs to medical equipment, and relates to a wireless inductive compensator interlocking device suitable for an externally mounted medical accelerator, and is a safety device for tissue compensator adapted to the current externally mounted medical electronic linear accelerator. Interlocking device for patients who routinely require radiation therapy to cover compensators. Background technique [0002] Medical electron linear accelerator: Accelerator for short, medical electron linear accelerator refers to an electron acceleration device that uses microwave electromagnetic fields to accelerate electrons and has a linear motion trajectory. The machine can generate high-energy rays (electron rays and X-rays). A large medical device used for radiation therapy of tumors or other lesions. [0003] Linear accelerator head: It is the general name of the window and its accessories for the medical electron linear accelerator to emit rays, and it...

AI Technical Summary

Problems solved by technology

If the compensator is not placed or detached, the accelerator cannot automatically stop the treatment, and this will cause a series of problems: (1) Repeated use of the same compensator: the risk of community infection increases; (2) It cannot be included as a parameter in " Treatment plan.plan": radiotherapy technicians are under a lot of pressure to review, and the risk of compensator forgetting increases; (3) The interlock device is missing after the compensator moves and slips: during the process of beam emission, due to involuntary factors of the patient (mostly physiological actions, such as: (breathing, coughing, etc.) caused the event that the compensator moved and slipped from the irradiation area, and the radiotherapy technician did not dispose of it in time (shutdown), etc., resulting in a radiation accident; (4) Uneven distribution of the dose curve: due to the fit of the compensator, the irradiation Uneven distribution of dose in the area
