Extension Description

SlicerRT Logo 2.0 128x128.png

SlicerRT is one of the themes of the SparKit (Software Platform and Adaptive Radiotherapy Kit) project with the goal of making 3D Slicer a powerful radiotherapy research platform. SparKit is a project funded by Cancer Care Ontarioand the Ontario Consortium for Adaptive Interventions in Radiation Oncology (OCAIRO) to provide free, open-source toolset for radiotherapy and related image-guided interventions.

The SlicerRT extension incorporates Plastimatch modules and algorithms.


Important note: BSpline Deformable registration and LANDWARP modules do not show up for Slicer 4.2 on Mac

Use Cases

  • Comparison of dose maps and dose volume histograms from various treatment planning systems
  • Evaluation of the effect of image-based non-rigid patient motion compensation

Similar Extensions

  • Plastimatch: SlicerRT and Plastimatch are complementary software libraries. Plastimatch focuses on delivering new computational methods radiotherapy, while SlicerRT aims for providing an easy-to-use interface for a wide range of stable, well-tested radiotherapy related features. SlicerRT uses Plastimatch internally for certain operations.
