摘　　要：目的了解广西医用电子直线加速器设备性能的质量控制水平,为卫生行政部门研究制定医用电子直线加速器卫生标准和质量控制检测规范提供技术支持。方法采用随机抽样方法,对广西部分医用电子直线加速器进行质控检测。结果2017—2019年累计检测118台次加速器,加速器质控检测(包括X射线和电子束)总初检合格率为56.8%,总复检合格率为96.6%;二级、三级医院加速器质控检测初检合格率分别为32.0%、62.2%,差异有统计学意义(P<0.05),初检合格率最低的指标是辐射剂量示值误差,其次是辐射野均整度。结论广西医用电子直线加速器质量控制水平有待提高;卫生行政部门应进一步加强对加速器质控检测的监督,定期开展加速器质控检测。Objective To understand the level of quality control in medical linear accelerator in Guangxi,and to provide technical support for the health administrative department to make related standards.Methods To select medical linear accelerators in Guangxi by random sampling method.Results A total of 118 accelerators were checked in 2017—2019,the initial inspection pass rates of medical linear accelerators were 56.8%and re-inspect pass rate were 96.6%.Conclusion The quality control level of the radiology institutions needs to be improved.The health administrative department should strengthen routine management,it is necessary to implement quality control in medical linear accelerator.
