Abstract
Objective The purpose of this study is to investigate the characteristics and rules of medical linear accelerator and its routine maintenance and repair methods. Methods In this study, a medical linear accelerator used in the radiotherapy department of our hospital was taken as an example to conduct a comprehensive statistical analysis on the faults that occurred in the past five years from 2012 to 2017, and the causes of the failures and the characteristics of the faults and rules were analyzed. Then the corresponding routine maintenance and fault repair methods were put forward. Results The failures of this hospital medical linear accelerator in 2012 to 2017 included: multi-leaf collimator (MLC) failure, beam system failure, operation and control system failure, vacuum inflation system and constant temperature water circulation system failure, mechanical failure. Among them, the failure rate of MLC was the highest (30.93%), and the mechanical failure was the lowest (3.09%). Conclusion There are many kinds of medical linear accelerator failures, and the causes of these failures are complicated. We should pay attention to the maintenance and maintenance of equipment and prevent the occurrence of faults in a targeted manner in routine work.关键词
