Adaptive from a Robust Perspective
Robust applies:
For residual uncertainties in intra- &
inter-fraction motion.
Adaptive applies:
Change/variation of systematic errors.
Drift, progressive anatomical changes
Adaptive requirement: more knowledge
Robust approach may reduce effort.
Formalize trade-off mathematically.
