Figure 5: (a) Comparison of dose-volume histogram for a prostate three-dimensional conformal radiation therapy with various electron densities associated with tube voltages (80–140 kVp) and (b) magnified view of dose-volume histogram for planning target volume only. Also note the plot of dV-dose-volume histogram in inset providing useful information where dose-volume histogram cannot be easily differentiated
