Summary
Multisource beam representations
– developed for several beam modalities
– allow modelling of individual machines by parameter settings
– actual implementations may vary with great impact on e.g.
narrow beam and IMRT performance
52
– automated methods exist for parameter setting from measured
data
– parameters can also be readily derived from Monte Carlo phase
space data
Be critical to your data!
For new, well controlled and standardized machines one
may consider using a standard set of data!
