Figure 5From: Optimization of extracranial stereotactic radiation therapy of small lung lesions using accurate dose calculation algorithmsComparison of DVHs for the 9 field plan as calculated with Pencil Beam and Collapsed Cone for the same number of Monitor Units. Normalization was performed to the isocenter for Pencil Beam. The volume of the CTV covered by the 95% isodose which is predicted by PC to be 100%, is only 61% if calculated by CC.Back to article page
