Conclusions
• VMAT just another flavour but faster because of
continuous irradiation but not better (more gantry angles
but unmodulated fluence per angle
)
• fan beam rotational IMRT (Tomo) offers independent bixel
optimisation and therefore more dose shaping
functionality
• in both cases fluence enters the patient from all (gantry)
angles sometimes requiring different optimisation
strategies
