Vox2Cortex: Fast Explicit Reconstruction of Cortical Surfaces from 3D MRI Scans with Geometric Deep Neural Networks

Vox2Cortex deforms a brain template to the inner and outer boundary surfaces of the cortex based on features extracted from the input MRI.

The obtained surfaces are geometrically accurate and topologically correct.

The novel curvature-weighted Chamfer Loss reweights the ratio between geometric accuracy and surface regularity locally based on ground truth curvature
