What Has Changed in the World of
Planning?
•
SBRT Planning
•
The goal SBRT is to deliver
very
high doses/fx to the target to
induce maximum damage
“ablative” doses
•
Aim to minimise the volume of healthy tissue receiving a high dose per
fraction
Dose to OARs is very important due to high dose/fx and increased
risk of toxicity
•
Traditional dose homogeneity is less of a concern
Up to 160% dose maximum is not uncommon
