Merged summary

TL;DR - A GPU-accelerated 3D mesh-refinement framework uses anatomical context and geometric constraints to improve pericardium segmentation in cardiac CT. As a model-agnostic post-processing step, it is especially promising for weak or out-of-domain initial segmentations.

  • Iteratively moves mesh vertices using a 3D vector field derived from anatomical rules.
  • Improves volumetric, surface, and anatomical metrics across high-resolution and sparsely annotated datasets.
  • Delivers larger gains on weaker initial segmentations.
  • Can potentially extend to segmentation of other anatomical structures.
