摘要
目的 :分析与探讨多层面螺旋CT机(multi-slicehelicalCT,MSCT)应用质量。材料和方法 :不同生产厂家生产的MSCT三台 ,用美国体模实验室(ThePhantomLaboratory)生产的CatphanTM体模以及美国Radcal公司生产的剂量测试设备对这三台MSCT进行应用质量检测。结果 :三台MSCT各有1项性能参数不合格 ,部分参数检测结果不理想。结论 :MSCT的剂量指数和场均匀性等参数的性能有待改善。
Purpose:To analyse and discuss the quelity of Multi-slice Helical CT(MSCT).Materials and Method:3 sets of MSCT.The CatphanTM developed by the phantom Laboratory in USA and the dosemeter developed by Radcal Corporation in USA were used to make the QA test on MSCT.Results:There was one disqualified parameter for each of 3 sets of MSCT,some other parameters were dissatisfactory.Conclusion:For MSCT,it is necessary to improve the performance in CTDI and uniformity.
