New CATMIL method improves brain MRI lesion segmentation accuracy

Researchers have developed a new objective function called CATMIL to improve the segmentation of small structures in brain MRI scans. This method combines standard segmentation loss with auxiliary terms that adaptively reweight voxel contributions based on connected components and introduce lesion-level supervision. Evaluations on the MSLesSeg dataset demonstrated that CATMIL enhances segmentation accuracy, lesion detection, and error control, particularly improving the recall of small lesions while minimizing false positives.

    Component-Adaptive and Lesion-Level Supervision for Improved Small Structure Segmentation in Brain MRI

    arXiv:2604.08015v2 Announce Type: replace Abstract: We propose a unified objective function, termed CATMIL, that augments the base segmentation loss with two auxiliary supervision terms operating at different levels. The first term, Component-Adaptive Tversky, reweights voxel con…
