Embodiment Construction

[0019] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0020] The present invention provides an intelligent joint guarantee control system for medical linear accelerators. Its core idea is to establish an auxiliary joint guarantee system for monitoring the water temperature, water pressure, and air-filled waveguide system in the medical linear accelerator water cooling system. The air pressure, the current of the titanium pump power supply, the opening and closing of the shielding jaws in the treatment room, and the faults of each subsystem, determine the corresponding operation according to the fault type, so as to realize the patient protection interlock, machine interlock and misoperation interlock.

[0021] In order to facilitate fault finding and troubleshooting, such as figure 1 As shown, the present invention divides machine fault into following several pieces: modulator system fault, accelerating tube ...

Abstract

The invention discloses an intelligent joint protection control system for a medicinal linear accelerator. The central thought is that: an auxiliary joint protection system is established and is used for monitoring water temperature and hydraulic pressure in a water cooling system of the medicinal linear accelerator, air pressure in a filled waveguide system, current of a titanium pump power supply, and faults of a switch on a shielding lead door for a treatment room and each subsystem, and determining corresponding operation according to the fault types so as to conveniently realize patient protection interlocking, machine interlocking and faulty operation interlocking.

Description

technical field [0001] The invention relates to the technical field of medical electronic linear accelerators for medical devices, in particular to an intelligent joint guarantee control system for medical linear accelerators. Background technique [0002] The joint insurance control system is set in the medical linear accelerator to ensure the safety of patients and operators, and to protect the machine during daily use, which is an essential function of the accelerator. Various factors need to be considered in the joint insurance control system, for example, the patient protection interlock is to avoid various hazards that may occur during the working process of the machine, such as overdose exposure and mechanical damage, and to ensure accurate treatment of the patient; there are some interlocks It is to prevent wrong treatment that may be caused by misoperation by the operator; machine interlock is to shut down the machine immediately when the machine components or subsy...
