Knee MRI Cartilage Analysis

View AI cartilage segmentation of knee MRI in 3D, measure cartilage thickness by region, and correct the mask directly in your browser.

AI AI Cartilage Segmentation Viewer

Upload a knee MRI together with its AI cartilage segmentation mask to view femoral and tibial cartilage in three planes and 3D, with cartilage thickness and area calculated automatically by region. Correct mis-segmented areas with brush, fill and auto-contour tools and save your edits. Saved versions can be compared with the original AI mask to see exactly what was changed.

Key users: orthopedic and radiology research teams, musculoskeletal imaging labs

HOW IT WORKS

Upload files once and they are organized into cases automatically. Open any case from the list to review and edit it.

  1. Upload Drag and drop the MRI, AI mask and edited mask files (nii.gz), or a whole folder.
  2. Automatic pairing Files are grouped into cases by name: X_0000 MRI, X AI mask, X_edited edited mask.
  3. Review and edit Open a case in the viewer. Each save is kept as a new version, and the latest one is shown.
