SpinalCordToolbox Spinal cord MRI segmentation in the browser

SCT segmentation in the browser

Segment spinal cord MRI locally in your browser.

Load NIfTI or DICOM spinal cord MRI, run browser-compatible SCT segmentation tasks, inspect overlays, and download outputs without uploading patient data.

Patient images, DICOM metadata, voxel values, segmentations, screenshots, and generated outputs stay on this computer.

Local-first workflow

  • Files are read into browser memory for viewing and analysis.
  • Public runtime and model assets may be downloaded when needed.
  • Patient-derived files and generated results are not uploaded by the app.
  • Long runs can continue if this site is allowed to stay active in your browser.

How It Works

1. Load MRI data

Drop NIfTI or DICOM files. Loading only displays the scan; processing starts when you run a task.

2. Choose an SCT task

Select a supported segmentation task and adjust threshold or cleanup settings if needed.

3. Inspect and export

Review overlays in NiiVue, toggle label stages, download NIfTI outputs, and run supported post-processing.
