摘　　要：目的对直线加速器质量控制检测文献报道中的不合格项目进行深入研究,分析质量控制检测中存在的问题,提出当前我国加速器质量控制检测工作的重点和发展方向。方法在CNKI数据库进行文献检索,对文献报道中各个检测项目的合格率及质量控制检测中存在的问题进行分析。结果在直线加速器质量控制检测的文献报道中,除了个别省份检测项目合格率均为100%外,大部分文献报道中均有不合格项目。X射线和电子线的检测项目在不同的文献报道中均有不合格情况发生。“剂量示值的误差”是出现几率最高的X射线不合格项目,同时也是出现几率最高的X射线和电子线合格率最低项目;其中X射线剂量示值的误差合格率最低者为2016年报道的73.5%,电子线剂量示值的误差合格率最低者为2017年报道的46.2%。结论要严格按照质量控制检测标准中要求的项目和周期实施检测。医院、放射卫生技术服务机构、卫生行政部门应各司其职,通力协作,重视和做好直线加速器质量控制检测工作,以进一步提高直线加速器质量控制水平。Objective To study the unqualified items in the reported quality control tests of linear accelerators,analyze the issues in quality control tests,and propose the key points and development directions for accelerator quality control test in China.Methods A literature review was conducted using the CNKI database to analyze the qualified rates of test items and the issues in quality control tests.Results In the literature on the quality control tests of linear accelerators,except for a few provinces where the qualified rates of all test items were 100%,unqualified items were reported in most of the literature.There were unqualified items related to X-ray and electron beam in different reports.Error of dose indication was the unqualified item with the highest occurrence rate in X-ray test,and the item with the lowest qualified rates in X-ray and electron beam tests.The lowest qualified rate of X-ray dose indication error was 73.5%in 2016,and the lowest qualified rate of electron beam dose indication error was 46.2%in 2017.Conclusion Tests should be carried out strictly according to the items and intervals specified by the quality control test standards.Hospitals,radiation health technology service institutions,and health administrative departments should each fulfill their respective responsibilities,work together,and place emphasis on ensuring effective quality control tests of linear accelerators to further enhance the overall quality control standards for these devices.
