Fig. 1From: Feasibility of automated proton therapy plan adaptation for head and neck tumors using cone beam CT imagesDose distributions for Pat2 and Pat5 from the original plan on the pCT and rpCT as well as the adapted dose distributions on the rpCT (rpCTadapt) and vCT (vCTadapt). The high and low dose PTVs are indicated in blue and green respectively. The spinal cord PRV is also shown. For the high dose PTV, the 95Â % dose level corresponds to 105Â % on the color bar, which is relative to the low dose PTV prescription. Hot spots correspond to 120Â % or more of the low dose PTV prescriptionBack to article page
