摘要
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。
To evaluate a domestic refillable flood field uniformity phantom, it was compared with a qualified phantom. The two phantoms were employed to measure the flood field uniformity and the spectrum in one set of γ camera. The results showed no lbvious difference in flood field uniformity (integral uniformity: p=0 0596, differential uniformity: p=0 0682) between the two phantoms and the shapes of spectrum were similar.
