【摘要】：目的:研制核医学成像设备SPECT质量控制测试系统软件,以满足SPECT设备质量控制需求。方法:以NEMA NU1-2007标准为依据,按照标准中相应的数据处理方法,建立各指标测试数据的处理分析模型,采用程序模块化设计、软件跨平台运行设计以及检测报告自动生成等技术实现软件系统。结果:SPECT质量控制检测系统的设计可实现主要性能指标固有均匀性、固有空间线性、固有空间分辨率、平面系统灵敏度、平面系统空间分辨率、断层空间分辨率和全身扫描空间分辨率等指标检测数据的处理分析。结论:该系统具有良好的稳定性、可靠性和输出结果的准确性,且操作简便易行;可配套国产通用SPECT性能检测模体套装,应用于不同厂商、不同型号的SPECT性能测试,既可满足年度状态检测需求,还可用于各医院的常规SPECT质量控制检测工作。
[Abstract]:Objective: to develop the software of SPECT quality control test system for nuclear medical imaging equipment, in order to meet the requirement of SPECT equipment quality control. Methods: according to the NEMA NU1-2007 standard, according to the corresponding data processing method in the standard, The model of processing and analyzing the test data of each index is established, and the program is designed by modularization. Results the design of the quality control and inspection system of the: SPECT can realize the inherent uniformity of the main performance indexes, inherent space linearity, inherent spatial resolution, and so on. The sensitivity of plane system, spatial resolution of plane system, spatial resolution of fault and spatial resolution of whole body scanning were analyzed. Conclusion: the system has good stability, reliability and accuracy of output results. It can be used in different manufacturers and different models of SPECT performance testing. It can not only meet the demand of annual state detection, but also can be used in the routine SPECT quality control inspection of hospitals.
