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
