GRACE — Whole-Head MRI Segmentation

GRACE is a UNETR-based model for automated whole-head MRI segmentation into 12 tissue classes, developed by the SMILE Lab.

Variants

grace_native.pth — operates in native MRI space
grace_fs.pth — operates in FreeSurfer conformed space (256³ @ 1mm isotropic)

Tissue Classes

See labels.json for the full 12-class label map.

Usage

Install the CROWN CLI and download this model:

pip install crown-cli
crown models download grace-native
