Claims
we present a diffusion-driven Learning-to-Optimize (L2O) method for end-to-end VMAT planning. A distribution-matching distilled diffusion model learns a clinically feasible manifold of fluence maps, enabling their one-shot generation. On top of this, an LSTM-based L2O module learns gradient update dynamics to swiftly refine fluence maps toward prescribed dose objectives during inference.
The learned fluence map manifold is clinically feasible and the LSTM module can learn stable gradient update dynamics that generalize to new patient geometries without post-hoc tuning or safety overrides.
A distilled diffusion model generates clinically feasible fluence maps for VMAT and an LSTM-based optimizer refines them to meet dose objectives, improving efficiency and deliverability on prostate cancer data.
