Modelling the MLC - 3
RaySearch, Raystation,
RayPhysics Manual v4.7
•MLC leaf ends are modelled straight (flat)
•No ray-tracing through leaf ends. Transmission through leaf tip is taken the same as the T&G transmission
•The MLC leaf tip position off-axis is corrected to account for difference in nominal position and radiation
field edge (one HVL of beam attenuation through leaf end).
•T&G modelled using an adjustable parameter (no ray tracing)
