目的对我市CT机进行应用质量控制检测并对结果进行分析,了解CT运行状况,为临床诊断提供数据支持。方法采用国家标准GB/T17589—1998《X射线计算机断层摄影装置影像质量保证检测规范》规定的性能检测指标、检测方法及评价方法。结果全部9项指标合格的CT机有16台,合格率达到80%;有4台CT机存在不合格项。结论茂名市CT机运行状态基本令人满意,多年来坚持CT检测对应用质量提高有帮助。二手机和陈旧型号CT机存在问题。应用质量控制检测十分重要,主要检测指标有待提高,国家标准有待修订。
Objective To test the quality control of CT machines in our city and analyze the results to understand the CT operation status and provide data support for clinical diagnosis. Methods Using the national standard GB / T17589-1998 “X-ray computed tomography imaging quality assurance testing specification” provides the performance testing indicators, testing methods and evaluation methods. Results All nine indicators qualified CT machine has 16, the pass rate of 80%; there are 4 CT machine there are items. Conclusion The running status of CT machine in Maoming city is basically satisfactory. It is helpful to insist CT inspection on improving the quality of application for many years. Second-hand machines and old models CT machine problems. Application of quality control testing is very important, the main testing indicators need to be improved, the national standards to be revised.
