摘要
目的检测单光子发射计算机断层成像系统(SPECT)的性能指标,评价其是否符合相关标准,确保临床诊断的准确性。方法用RGRMS-2012型SPECT性能模体对SPECT的固有计数率、固有均匀性进行检测,依据相关标准对检测结果进行判断,对不符合项进行修正,确保诊断的准确性。结果该SPECT的固有计数率、固有均匀性符合相关标准。结论设备在日常使用中的磨损、老化情况会对设备性能产生影响,建议定期进行设备状态检测,保证设备的可靠运行。
Objective To evaluate whether SPECT conforms to the requirements of national standards by testing its performance indicators in order to ensure the accuracy of clinical diagnosis.Methods The inherent counting rate and intrinsic uniformity of SPECT were detected by RGRMS-2012 performance phantom of SPECT. According to related standards, the test results were judged and the indicators which did not meet the requirements of the standards were corrected in order to ensure the accuracy of diagnosis.Results The inherent counting rate and intrinsic uniformity of SPECT conforms to the requirements of related standards.Conclusion Wear and ageing of equipment will affect its performance, which indicates that the state inspection of related equipment should be conducted regularly in order to ensure the reliability service of related equipment.
