Example 1: Modelling the MLC in Elekta Oncentra
Physics and Algorithms v4.3
Leaf Ends and Transmission and Tongue & Groove effect
•
Each MLC leaf end is modelled
round and ray-tracing through
this is done to account for
occlusion of the direct beam
source
•
Transmission through jaw and
MLC edges determined through
ray-tracing models the T&G
effect
