Figure 5. A dose–volume histogram (DVH) of an example patient with prostate carcinoma and nodal involvement (with right (Node_RT) and left (Node_LT) nodes considered separately). The organs at risk considered are the bladder, small bowel and rectum. The dose values are presented for the two cases: (i) before (BEF) shown as points and (ii) after (continuous lines) leaf sequencing with the planning target volume (PTV) dose being normalized to 70 Gy. Arrows indicate the increase in the dose delivered to the volume of interest due to leaf-sequencing effects.
