RaySearch – Algorithm – Collapsed cone
❑
Effective density basis for the TERMA calculation – implicitly transport in
medium
❑
Collapsed cone implemented as dose-point of view
❑
Same effective density used during scaling of cones/pipes.
❑
…the electron stopping power is assumed to scale with the effective density
i.e. they are assumed to be material dependent in the same way.
o
Water-like medium with a scaled mass-stopping power
o
This is converted to dose-in-water by the effective density ratio
❑
Thus;
