Figure 4.

CTV DVH bands of the four patients, indicating the robustness of the beams chosen by different methods. The situation with only range uncertainty is shown on the left and situation with only setup uncertainty is shown on the right. The worst D95% of each method is labeled by reference lines in the x‐y plane. The two CTVs in the H&N #1 patient are plotted together in the third row, and the three CTVs in the H&N #2 patient are plotted together in the fourth row, with different transparencies.
