Abstract
In clinical practice, plan quality is judged based on dosimetric indices. However, for the purpose of efficiency, typical automated planning methods do not directly optimize dosimetric indices. This creates a mismatch between what is optimized and what is evaluated. A bi-objective optimization approach was recently proposed that directly optimizes dosimetric indices, finding many high-quality plans with different trade-offs between target coverage and organ sparing. This allows for insightful comparison of high-quality plans and patient-specific plan selection. We can now generate such sets computer-aided in as little as 30 seconds by applying GPU acceleration, which permits use in clinical practice.
