•
Measure fluence profiles in air with removed applicator, field
settings varied with the photon collimators
•
Optimize source phase space parameters to fit measured
profiles
•
Generate source phase space electrons and propagate
them with the photon collimators at preset values and the
applicator mounted (no insert) to the exit phase space
•
Parameterize the exit phase space

•
Generate exit phase space electrons, discard those who
stem from areas blocked by the insert
•
Add collimator scatter electrons and treatment head photons
•
Propagate the generated particles into the patient
