Dealing with uncertainties

Robust optimisation – What is a good robustness metric?

Single voxel dose ‘spectrum’ due to positioning errors. Each is possible on each fraction of delivery

Voxel dose ‘spectrum’ due to positioning errors after n- fractions. Positioning errors assumed to be random errors

Fractionation

1 fraction

30 fraction

Example reduction of single voxel dose uncertainty (over full treatment) as a function of number of fractions
