Dynamic range optimization for treatment time reduction in respiratory‐gated proton therapy using RayStation v2025

Dynamic range optimization is an effective, planning-based method to reduce treatment time in respiratory-gated proton therapy, operating independently of patient cooperation or system modifications. The developed RayStation-integrated tool enables clinicians to identify the optimal patient-specific dynamic range, balancing efficiency gains against acceptable dosimetric quality, particularly for organs-at-risk adjacent to targets. This approach provides a technical foundation for individualized dynamic range selection during treatment planning.
