Research questionHow can brain MRI super-resolution preserve continuous tissue mixtures at partial-volume tissue transitions?Partial-volume voxels contain continuous mixtures of neighboring tissues, but they occupy relatively little image area and can be underrepresented by full-image reconstruction objectives. Binary tissue boundaries also provide an incomplete description of these transitions.

It is evaluated at 2× and 4× super-resolution on IXI, with a PVE-free backbone also tested on fastMRI, and with zero-shot whole-tumor segmentation on BraTS2023.research paper · Sep 2, 2026
