Fig. 2From: Cardiac-sparing radiotherapy for locally advanced non-small cell lung cancerCardiac dose-volume measures plotted for baseline and re-optimized plans. The re-optimized plans were designed to reduce a MDHeart, b VHeart-50-Gy and c VLAwall-63-Gy. Basic, moderate and ambitious target levels for the different dose-volume measures are shown as dotted lines. In d baseline MDHeart values are plotted against the PTV/Heart overlapBack to article page
