本文通过对国产和进口泛源模型的比校测试，评价国产模型的性能。使用两个模型分别测试同一台γ相机的固有泛源均匀性和能谱。结果显示两组固有泛源均匀性结果无显著差异（微积分均匀性分别为０．０６８２、０．０５９６），能谱基本相同。表明国产模型可有效用于γ相机和ＳＰＥＣＴ的质量控制。 This paper evaluates the performance of domestic models by comparing and calibrating domestic and imported pan-source models. Two models were used to test the intrinsic homogeneity and energy spectrum of the same gamma camera respectively. The results show that there is no significant difference between the two groups in the inherent uniformity of homogeneity (the calculus uniformity is respectively 0.0682 and 0.0596), and the energy spectra are basically the same. It shows that the domestic model can be effectively used for the quality control of γ camera and SPECT.
