Preserving Anatomical Continuity: Three-Stage Pipeline for Colon Segmentation in 3D Abdominal CT Scans

The paper presents a three‑stage pipeline for colon segmentation in 3D abdominal CT scans that preserves anatomical continuity. First, a deep‑learning model generates an initial segmentation; second, centreline bridging reconnects disjoint regions; third, a reconstruction stage refines the continuity. Experiments on the TotalSegmentator and RAOS datasets show that the method improves topological consistency while keeping segmentation accuracy high.
