摘　　要：目的通过对21台单光子发射计算机断层扫描装置(SPECT 机)的性能检测结果分析,探讨提高 SPECT 机的影像质量控制措施。方法根据2007版NEMA(美国电气制造商协会)标准及各厂家标准,通过图像分析软件,对21台 SPECT 机进行性能检测。结果不合格检测项目主要集中在固有积分均匀性和固有空间微分线性。结论重视日常质控工作,提高质控意识和技术水平,可有效保证图像质量。Objective To improve the image quality control of SPECT Equipment by analyzing the performance test results of 21 SPECT Equipment. Methods Performance was done on testing on the 21 SPECT Equipment with image analysis software,following the 2007 edition of the NEMA（ National Electrical Manufacturers Association） standard and the standards of manufacturers. Results The unqualified items mainly appeared in the intrinsic integral uniformity and the intrinsic spatial differential linearity. Conclusion To effectively guarantee the image quality,higher awareness of quality control process,stronger emphasis on daily control work,and better technical capability are necessary.
