Example 4: Source modelling in Varian Eclipse Manual: Eclipse Algorithms Reference Guide v13+

Beam source: point source

•

• Effective source intensity distribution model: 2D Gaussian • Effective Source distribution parameters: tuning parameters during the beam configuration • Geometric penumbra is modelled accounting for collimator/MLC position with respect to the finite source size (but not shape of the collimator jaw end)
