Fig. 5From: Effects of the Bragg peak degradation due to lung tissue in proton therapy of lung cancer patientsLeft side: Cumulative dose-volume histogram for the CTV and trachea for patient 1 and the beam direction 270° for both the non-modulated case and the modulated cases based on modulation powers between 100 μm and 800 μm. Right side: depth dose curve along the center of the beam. The positions of the body, the lung and the CTV are marked by dashed black linesBack to article page
