Example 3: Source modelling in RaySearch Raystation
Manual: RayPhysics Manual v4.7
•
Beam source: finite size
•
Source intensity distribution model:
2D Gaussian
•
Source intensity distribution parameters:
values obtained through automated
beam model optimisation procedures
•
The influence of variations of the primary source as projected over the pixels of
the energy fluence matrix is modelled
•
Geometric penumbra is modelled accounting for collimator/MLC position with
respect to the finite source size
(but not shape of the collimator jaw end?)
