Cost function vs. plan evaluation

The dose distribution resulting from (unconstrained)

optimisation typically contains

•Features you requested and you obtained

•Features you requested and you did not obtain

•Features you did

not

request

•Neutral features

•Negative features (you left a ‘hole’ in the cost

function, and the optimisation took advantage from

it)

•Positive features (you got them ‘for free’, as a

byproduct of other features)
