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
