Proton arc therapy (PAT) faces two key challenges: minimizing treatment delivery time and eliminating gantry rotation velocity fluctuations. To address these, this study proposes a novel workflow that enables true dynamic arc delivery.

This study aimed to develop a novel optimization framework for spot-scanning proton arc therapy (SPArc) to simultaneously achieve highly uniform beam delivery time (BDT) across control points, improved delivery efficiency, and optimal dose distribution.

Low-field MRI suffers from intrinsically low SNR, which limits image quality and slows wide clinical adoption. Deep learning–based denoising shows strong promise, yet supervised training requires paired high-quality references that are rarely available for lo...
