❑ For the lateral scaling, a discretization in 16 perpendicular directions is used and for each an equivalent path length is determined.

❑ While the variable lateral scatter considerations improve the algorithm performance in lung, it does not change the fact that the medium is still uniformly considered water-equivalent and the dose is thus reported to water. ❑ Different heterogeneities can be modified as scaled water, thus or
