ObjectiveTo analyze the common faults of 23EX VARIAN linear accelerator MLC and provide the experience for the maintenance of the accelerator. Methods To observe the in the treatment process of the machine failure, observation 4DTC treatment control computer, through the MLC test software to check the fault information to find fault, analysis of the causes of failure, to solve the problem.ResultsAfter scientific analysis, symptomatic treatment, the effective elimination of failure, the system returned to normal operation, maintenance and maintenance for the machine has accumulated experience.Conclusion The use of MLC is high and easy to malfunction. To explore a set of effective method to repair the MLC fault can improve the machine performance, to ensure that the effect of the intensity of radiation therapy.
