Fig. 7From: Assessment of dose perturbations for metal stent in photon and proton radiotherapy plans for hepatocellular carcinomaDVH according to the stent’s position and angle compared to no-stent for the proton beam. DVHs calculated from the GB stent a and GI stent b placed at an angle of 0°, DVHs calculated from the GB stent c and GI stent d placed at an angle of 45°, and DVHs calculated from the GB stent e and GI stent f placed at an angle of 90°Back to article page
