Representative axial isodose distributions for treatment of a prostatic adenocarcinoma. Targets and normal tissues are represented as color washes. Slices depicting treatment of CTV2 (seminal vesicles) as well as CTV1 (prostate) are shown in left and right panels for SFIB (A), SFUD with sequential boost (B) and IMPT (C) plans. The dose volume histogram is shown in (D) (solid lines, SFIB; dashed lines, SFUD and dotted lines, IMPT).
