Example 2: Source modelling in Philips Pinnacle 3 Manual: Physics Reference Guide v9.10 • Beam source: finite size

• Effective source intensity distribution model: 2D Gaussian

• Effective source intensity distribution parameters: values obtained through the Automodelling procedures • Geometric penumbra modelled accounting for collimator/MLC position with respect to the source (but not shape of the collimator jaw end?)
