Fig. 3From: Optimizing the prescription isodose level in stereotactic volumetric-modulated arc radiotherapy of lung lesions as a potential for dose de-escalationExample dose distributions achieved with varying PIL–optimized VMAT plans in the axial plane and the dose–volume histograms (DVH) of selected organs. The PILs are displayed with 100% corresponding to the treatment dose of 54 Gy. Inlet shows the magnified ipsilateral lung DVHBack to article page
