摘　　要：目的了解放射诊疗设备质量控制状况,探索设备性能不合格原因及其控制策略研究,为提高设备性能合格率提供科学依据。方法按照国家相关标准要求的质量控制检测规范,对广西111家医院的467台放射诊疗设备进行质量控制检测,设备质量控制检测合格率比较用卡方检验。结果广西放射诊疗设备质量控制总合格率为80.51%,X射线影像诊断、放射治疗、核医学设备质量控制合格率分别为81.6%(346/424)、75.68%(28/37)和33.33%(2/6),核医学设备质量控制合格率低于X射线影像诊断和放射治疗设备(P<0.05)。DR和屏片摄影机质量控制不合格主要原因为光野与照射野四边的偏离不达标;CT、SPECT、医用电子加速器和后装机不合格的主要原因分别是CT值线性、固有非均匀性、校准点吸收剂量和源到位精度检测不达标。结论广西放射诊疗设备质量控制合格率较低,需进一步针对不合格项目加强设备的质量控制检测。Objective To provide scientific basis for improving the qualified rate of equipment performance,through understanding the qualified situation on quality control of medical radiative diagnostic equipment in Guangxi,and exploring the reasons of the unqualified equipment performance and control strategy. Methods The quality control testing of 467 medical radiative diagnostic equipment from 111 hospitals in Guangxi were carried out,according to test specifications on quality control of the relevant national standards. Chi-square test was used to the qualified rate in the different apparatus of radio diagnosis and radiotherapy. Results The qualified rate on the quality control of medical radiative diagnostic equipment in Guangxi was 80.51%. The qualified rate on quality control of X-ray imaging diagnosis,radiative treatment,and nuclear medical equipment were 81. 6%（346/424）,81. 6%（28/37） and 33. 33%（2/6）,respectively. The qualified rate on quality control of nuclear medical equipment is lower than the X-ray imaging diagnosis and radiotherapy equipment（ P 0. 05）. The reason on the unqualified quality control of DR and X-ray imaging equipment was that the quadrilateral deviation of the light field and radiation field was substandard. The main reasons of the unqualified CT,SPECT,medical electron accelerator and afterloader were that CT value linear,inherent inhomogeneity,calibration point absorption dose and source precision detection was substandard,respectively. Conclusion The qualified rate on the quality control of medical radiative diagnostic equipment in Guangxi is low,and the quality control test for unqualified equipment should be improved further.
