本文提出了一种基于部分注量近似的光子束剂量分布计算模型。该模型的预测进行了比较与剂量分布测量分层幻影组成的铝和聚苯乙烯，光子束的能量范围从60 Co到24 MV。
A model based on an approximation called the partial fluence approximation is presented for the calculation of dose distributions in the vicinity of medium interfaces in photon beams. The predictions of the model are compared with dose distributions measured in layered phantoms consisting of aluminum and polystyrene, for photon beams ranging in energy from 60Co to 24 MV.
