Deep learning–based dose prediction to improve the plan quality of volumetric modulated arc therapy for gynecologic cancers

Medical Physics (Lancaster), 2023
Background In recent years, deep‐learning models have been used to predict entire three‐dimensional dose distributions. However, the usability of dose predictions to improve plan quality should be further investigated.
