Open-source radiation therapy
research toolkit for 3D Slicer

  1. Extends 3D Slicer
  2. Hub for RT analysis
  3. Open-source

Builds on a dynamic platform

SlicerRT is an extension of 3D Slicer, a free, open source software for visualization and image analysis. SlicerRT can be installed from the 3D Slicer Extension Manager on Windows, Mac, and Linux to leverage the advanced features of 3D Slicer in adaptive radiation therapy research.

Covers common RT research workflows

SlicerRT includes close to 20 modules that provide tools for radiation therapy research, including advanced deformable registration methods powered by the Plastimatch library. Standard DICOM-RT format is supported, thus integrating with the treatment planning systems.

SlicerRT is open research

Our development and research work is public, including source code, data, manuals, presentations, etc. SlicerRT is distributed under the BSD-style Slicer license allowing academic and commercial use without any restrictions. See our OpenHub site for further details.
