三套10 MV的X射线零面积体模散射校正因子（Sp）已获得使用三种方法。这三种方法都是基于Bjärngard-Petti外推原理。这三组数据假定初级吸收剂量的横向CPE（带电粒子平衡）。使用最可靠的数据集，一组10 MV的X射线SMR（散射最大值比）的生产和参数化。对于2.5 cm深度处的零面积Sp校正因子，参数化表达式给出Sp（0; 2.5）= 0.931，Rice-Chin Monte Carlo模拟给出Sp（0; 2.5）= 0.927。前者仅比后者大0.4%。
Three sets of 10 MV x-ray zero-area phantom scatter correction factors (Sp) have been obtained using three methods. The three methods are all based on the Bjärngard-Petti extrapolation principle. The three sets of data assume lateral CPE (charged particle equilibrium) for the primary absorbed dose. Using the most reliable set of data, a set of 10 MV x-ray SMRs (scatter-maximum ratios) is produced and parameterized. With respect to the zero-area Sp correction factor at a depth of 2.5 cm, the parameterized expression gives Sp (0; 2.5) = 0.931 and a Rice-Chin Monte Carlo simulation gives Sp (0; 2.5) = 0.927. The former is only 0.4% larger than the latter.
