Z-curve results for the GYN patient cases. (a) ~ (c) correspond to the $\frac{1}{2}/\frac{1}{4}/\frac{1}{8}$ dose level cases, respectively. The values of β_a ~ β_e are 0.5 × 1.2⁻¹⁰, 0.5 × 1.2⁻⁵, 0.5, 0.5 × 1.2⁵ and 0.5 × 1.2¹⁰, respectively. The arrows indicate the suggested β of the maximum curvature points.
