Figure 4

Dose–volume histograms for the spinal cord at V 11,0 . The volume is located at 11 cm-distance from the isocenter at a 0° azimuthal angle. Histograms are drawn according to the applied angular increments (2°, 4°, 6°, and 10°) in the spherical planning target volume for (a) S2 (2-cm diameter) and (b) S4 (4-cm diameter).
