Conclusions
•
offline adaptive
setup correction and margin adapting protocols with
clinically proven benefits and high efficiency to reduce systematic errors
•
online adaptive
schemes can further reduce uncertainties for the price
of more frequent imaging, but there is a lower limit for margin reduction
provocative thought:
a single adaptation – if well implemented and its effects
evaluated thoroughly – is better than some ‘latest’ complex IGRT/ART scheme
with daily imaging and repeat adaptations
– unless its benefits are clearly proven with treatment simulation
approaches/patient data.
