Figure 4.

Dose distribution comparison in the same axial slice of one example case between (A) the automatic plan and (B) the clinical plan. The thick green line is the 95% isodose line, and the thin purple line is the PTV_Eval contour on this slice. The white arrows point to the same position at the edge of the lung (note the distance to the 95% isodose line). This case shows how the automatic plan improves the sparing of the lung without sacrificing the PTV coverage. PTV indicates planning target volume.
