What algorithms can different beam data sets support?
Beam data objects
Fluence/Dose engines
Direct use of dose profiles/output
factors
•No explicit treatment head modelling
•Dose calculations based on
correction factors from geometrical
scaling and attenuation
Description of individual particles
•Explicit treatment head modelling
yielding
phase space
of individual
particles
Description of sources extracted from
measured dose profiles/output factors,
or from a phase space list of particles
•Explicit treatment head modelling
yielding fluence distributions
•Dose calculations from fluence using
kernel superpositions OR explicit
transport calculations
Mixed approaches also possible!
