Two Model Types

 Knöös et al.: A. Models primarily based on equivalent path length for inhomogeneity corrections, where electron transport is not separately modeled , and the density changes are sampled along the 1D (longitudinal) primary rays. Ex: Eclipse PB, OMP PB, XiO Convolution B. Models able to treat in an approximate way the electron transport as well as the secondary photon transport in the medium accounting for density changes, sampled along the full

three dimensions (longitudinal and lateral) . Ex: Pinnacle CC, Eclipse AAA, OMP CC, XiO Convolution/Superposition
