2. inhomogeneities
The method inherently accounts for inhomogeneities assuming
material properties are constant within each computational element
(!!! restriction on computational element size !!!)

, μ
s,l,g
•
primary fluence ray tracing
•
dose calculation
(note that D is calculated as a post processing operation)
