TOC graphs for fraction size and fraction number variation. TOC graphs for prostate 3D-CRT plan showing trade-off between TCP and NTCPGI as a function of (A) the dose-per-fraction scale factor (at constant fraction number) and (B) the number of fractions N (at constant fraction dose). The initial plan (39 × 2 Gy) is marked (○) at the 100% dose level and at N = 39, respectively.
