Figure 1. (a) Dose distribution of dynamic conformal photon therapy. (b) Dose distribution of proton boost therapy. Lateral opposed portals using proton beam can provide good dose coverage to the prostate and reduce the unnecessary irradiated volume of both the ventral and dorsal portion of the body. Isodose lines: orange, 105%; magenta, 100%; yellow, 95%; light green, 90%; light blue, 80%; light purple, 50%; purple, 20%. Red line shows the planning target volume.
