Sensitivity to uncertainties
•
Families of DVHs covering all setup
and proton range uncertainties
considered
•
Bands are an effective measure of the
sensitivity to uncertainty
→
the wider
the band, the greater the sensitivity
•
Solid lines are DVHs for the nominal
dose distribution
•
CTV coverage for the robustly
optimized plans is less sensitive to
uncertainties
