Table 1 Condition functions of typical objectives
From: Applying pytorch toolkit to plan optimization for circular cone based robotic radiotherapy
Objectives | g |
|---|---|
Max dose | \(H(D_{i} - D_{i}^{0} )\) |
Min dose | \(H(D_{0} - D_{i}^{0} )\) |
Uniform dose | 1 |
Max DV | \(\left\{ {\begin{array}{*{20}c} {H(D_{i} - D_{i}^{0} )} & {{\text{head}}} \\ 0 & {\text{others }} \\ \end{array} } \right.\) |
Min DV | \(\left\{ {\begin{array}{*{20}c} {H(D_{i}^{0} - D_{i} )} & {{\text{tail}}} \\ 0 & {{\text{others}}} \\ \end{array} } \right.\) |
