Fig. 2From: Dosimetric feasibility of 4DCT-ventilation imaging guided proton therapy for locally advanced non-small-cell lung cancerIsodose distributions of an example patient showing multiple slices, from (a) IMRT, (b) anatomical double scattering proton treatment (aDSPT), (c) functional double scattering proton treatment (fDSPT), (d) anatomical intensity modulated proton treatment (aIMPT), (c) functional intensity modulated proton treatment (fIMPT) plans. The PTV is highlighted in red and high-functional lung regions are in orangeBack to article page
