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.
