The algorithn proposed in 1976 to allow for the influences of tissue inhomogeneities in electron beam dose distributions has been improved. A factor adopted from Sternheimer corrects for differences in lateral displacement by multiple scattering within the inhomogeneity resp. the equivalent layer of the homogeneous medium. The algorithm has been tested by direct comparison with Monte Carlo computations for the example of cylindrical cavities in carbon at Eo=10 MeV and resulted in a very close approximation.
1976年提出的用于考虑组织不均匀性对电子束剂量分布影响的算法已得到改进。采用了斯特恩海默提出的一个因子,用于校正不均匀性内多次散射引起的横向位移差异,即均匀介质的等效层内的横向位移差异。该算法已通过与蒙特卡罗计算直接比较进行了测试,以Eo = 10 MeV的碳圆柱腔为例,结果得到了非常接近的近似值。
