About MNC File Viewer

The View MNC File Online tool is a specialized, browser-based utility designed to open, inspect, and visualize MINC (Medical Imaging NetCDF) files. Whether you are a researcher, medical student, or developer working with neuroimaging data, this tool provides a quick way to check file contents without installing heavy software like MINC Toolkit or FreeSurfer.

What is an MNC file?

An .mnc file is a medical imaging data format developed by the Montreal Neurological Institute (MNI). It is widely used in neuroimaging research to store MRI, PET, and CT scan data. The format is based on NetCDF (Network Common Data Form) or HDF5 (in newer MINC2 versions), allowing it to store multi-dimensional arrays of data along with rich metadata.

Key Features

  • Instant Visualization: View axial slices of your medical images directly in the browser.
  • Metadata Inspector: Extract and export header information, dimensions, and variable attributes.
  • Client-Side Privacy: Your files are processed locally in your browser. No data is ever uploaded to a server.
  • No Installation: Works on any device with a modern web browser (Chrome, Firefox, Edge, Safari).

How to Use

  1. Upload: Drag and drop your .mnc file into the upload area, or click to select a file.
  2. Visualize: Use the "Visualizer" tab to scroll through the image slices using the slider. Adjust brightness and contrast to see details clearly.
  3. Inspect: Switch to the "Metadata" tab to view technical details like dimensions, voxel sizes, and history.
  4. Export: Download the metadata as a JSON file or save the current image slice as a PNG.

Frequently Asked Questions

Yes, this MNC viewer is 100% free and open for everyone. There are no hidden costs or subscriptions.

Does it support MINC2 (HDF5) files?
