Summary

The community of Slicer developers is proud to announce the release of Slicer Nightly.

  • Slicer Nightly introduces
    • an improved App store, known as the extension manager, for adding capabilities to Slicer. More than 50 plug-ins are currently available.
    • close to 400 feature improvements and bug fixes lead to improved performance and stability.
    • augmentation of many modules.
  • Click here to download Slicer Nightly for different platforms and find pointers to the source code, mailing lists and bug tracker.
  • Please note that Slicer continues to be a research package and is not intended for clinical use. Testing of functionality is an ongoing activity with high priority, however, some features of Slicer are not fully tested.
  • The Slicer Training page provides a series of courses for learning how to use Slicer. The portfolio contains self-guided presentation and sample data sets.

The main slicer.org pages provide a guided tour to the application, training materials, and the development community. New users should start there because we try to keep the pages organized and up to date.

What is 3D Slicer

Slicer is a community platform created for the purpose of subject specific image analysis and visualization.

  • Multi-modality imaging including, MRI, CT, US, nuclear medicine, and microscopy
  • Multi organ from head to toe
  • Bidirectional interface for devices
  • Expandable and interfaced to multiple toolkits

There is no restriction on use, but permissions and compliance with rules are responsibility of users. For details on the license see here
