MedVol-R1: Reward-Driven Evidence Grounding for Volumetric Reasoning Segmentation arXiv:2605.26621v1 Announce Type: new Abstract: Volumetric Reasoning Segmentation (VRS) aims to segment a target region in a 3D medical scan from a free-form clinical query, where the referent is often implicit and requires both medical knowledge and volume-grounded reasoning. Existing methods typically rely on specialized segmentation tokens to connect language with mask decoding, but this coupling collapses the
