Fig. 6: Overview of the proposed ScarElastic framework.
From: ScarElastic: continuous elasticity field modeling for myocardial scar delineation in LGE-CMR
Inputs include the myocardium mask, wall thickness map, and LoG edge features, concatenated with LGE-CMR images. A 3D U-Net backbone with squeeze-and-excitation (SE) blocks extracts hierarchical features. The upper branch models the scar probability, while the lower branch estimates stiffness-related features; both are fused into a continuous elasticity field. The elasticity-aware regularization enforces topological consistency and smoothness. Labels in the diagram highlight each processing stage (Input → Feature Extraction → Elasticity Modeling → Outputs).
