Figure 6From: Optimization of extracranial stereotactic radiation therapy of small lung lesions using accurate dose calculation algorithmsComparison of DVHs for the optimized plans, calculated with Collapsed Cone: a) CTV b) right lung. Normalization was performed to the dose encompassing 95% of the volume for better visualization. The highest dose homogeneity is achieved by the 1/10 weighting for one peripheral segment per beam (black line), while the dose to the lung is even slightly lower than for the 9 field plan.Back to article page
