Abstract Objective To discuss the value and significance of application in quality control by measurement and analysis of intrinsic uniformity of 26 detectors of 13 SPECT Equipment.Methods According to the NEMA standard and the standard of each manufacturer,test the inherent uniformity performance of the SPECT equipment by using image analysis software.Results The qualification rate of integral proper uniformity is 92.3%.The qualification rate of Inherent differential uniformity is 61.5%.Conclusion Inherent uniformity is an important index to ensure the image quality of SPECT equipment.The quality control must be carried out according to the rules.
