Depicting the Biological Target Volume=
BTV
Local relapses can be due to cellular or micro-
environment clusters that resist to standard
homogeneous dose.
Metabolic imaging can help define radioresistant
clusters
Biological Target Volume
New radiotherapy techniques allow a precise
targeting of BTV
Optimisation of radiotherapy can be performed with
Dose-painting
: delivering heterogenous dose guided
by metabolic imaging
