clDice - a Novel Topology-Preserving Loss Function for Tubular Structure
Segmentation

• varying anatomical structure brings varying sets of challenges, and may require tailored solutions unique to their topology
• literature on biplanar x-ray to 3d segmentation mostly focused on new architecture design proposals which are anatomy-agnostic, Moving forward, we should probably focus on clinical downstream-task specific challenges/gaps.
• we unearth these issues in this study, thanks no less to publicly available CT bone segmentation datasets. We hope to bring the attention of the community into more nuanced aspects of x-ray to 3d segmentation
• In many ways, this is similar to widely studied segmentation problem except that there is a dimensionality discrepancy between input(2D) and output(3D). Many of the problems faced and solutions proposed can directly be applied as in case of tube-like structure of rib.
