Why this choice, what about the other 10%?
- Also for maximally conformal dose distributions,
dose is not zero outside the 95% isodose
in 10% of cases the CTV sticks (partially) outside the
real (= blurred) 95% isodose
small pieces may get dose lower than 95% but
still high
- real dose distributions are
