南阳市78台CT机质量控制检测与分析

目的 通过对我市78台CT机影像质量控制检测抽查，了解该市CT机应用质量现状，根据存在问题探索其对策。方法 按照GB/T 17589-2011《X射线计算机断层摄影装置质量保证检测规范》规定的性能检测指标对CT机进行检测和评价。结果 在抽查的78台CT机中，10项指标全合格的64台，合格率达到82.05%，有14台CT机存在不合格项。结论 抽查的CT机总体性能状况良好，但放射诊疗机构质量控制淡漠是造成CT质量控制检测不合格的主要原因，放射诊疗机构应做好CT机采购过程的技术把关和使用过程中的预防性维修保养工作。

Detection and analysis of the quality control for 78 CT machines in Nanyang City

Objective To know the current quality situation of CT machines in this city based on image quality control testing of 78 CT machines and to explore its countermeasures according to the existing problems.Methods The CT machines were tested and evaluated according to GB/T 17589-2011 "X-ray computed tomography device quality assurance testing specifications".Results Among 78 CT machines, the 64 were qualified for all 10 indicators, the qualified rate was 82.05%, 14 CT machines have some unqualified indications.Conclusion The overall performance of these sampling CT machines is good.however, the indifference to the quality control of the radiological diagnosis and treatment insitutions should be the main reason for the unqualified quality control test of CT. Radiological diagnosis and treatment institutions should do a good job in the procurement process of CT machines and preventive maintenance work in the process of using.
