About this dataset

A collection of MedSeg's highly detailed single-case teaching atlases, each labelling one anatomical theme in depth - cerebral, neck, abdominal and pelvic vasculature, pelvic musculature, lung lobes/vessels/airways, deep neck spaces, cervical lymph node levels, the urinary system, and an esophageal-cancer case.

What you can do with it in MedSeg

Copied cases behave like normal project series - the public image bytes are linked, not duplicated, so copies are instant and take no extra storage.

  1. Copy cases into a project.
    Filter, multi-select, copy - reference masks come along if you want them.
  2. Run AI segmentation.
    TotalSegmentator, MRSegmentator, nnInteractive 3D clicks/scribbles, or text-prompted VoxTell.
  3. Edit and measure.
    Brush, lasso, fill, oblique planes, volumes in ml - in the browser.
  4. Train your own nnU-Net.
    Correct masks on a handful of cases and train a custom model on hosted GPUs.
