目的统计分析黑龙江省34台在用医用电子直线加速器性能检测结果,对不合格项目原因进行分析,提出改进意见和建议。方法依据国家职业卫生标准GB15213-94、GB/T19046-2003、GBZ126-2011中提出的方法,对医用电子直线加速器进行检测。结果黑龙江省在用医用电子直线加速器初检合格率为67.6%,经校准调试后合格率为94.1%。结论造成加速器质量控制结果不合格的因素多,但绝大部分是可以避免和减少的,少数医院对质量控制观念淡薄,相应工作需要加强。
Objective To analyze and analyze the performance of 34 medical linear linacs in Heilongjiang Province, analyze the causes of unqualified items, and give suggestions and suggestions for improvement. Methods According to the methods proposed in National Occupational Hygiene Standards GB15213-94, GB / T19046-2003 and GBZ126-2011, the medical electron linear accelerator was tested. Results In Heilongjiang Province, the first pass rate of medical electron linear accelerator was 67.6%, and the passing rate after calibration was 94.1%. Conclusion There are many factors causing the unacceptable quality control of accelerator, but most of them can be avoided and reduced. A few hospitals have weak concept of quality control and corresponding work needs to be strengthened.
