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