Extension Description

SlicerRT Logo 3.0 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 Ontario and 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.
  • Additional information for users can be found on the User's Guide page

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.
  • Gel Dosimetry: Slicelet facilitating a streamlined workflow to perform true 3D gel dosimetry analysis for commissioning linacs and evaluating new dose calculation procedures
  • Film Dosimetry: Slicelet supporting workflow to perform 2D film dosimetry analysis for commissioning new radiation techniques and to validate the accuracy of radiation treatment by enabling visual comparison of the planned dose to the delivered dose
