Extensions

Listed below are extensions added, removed or updated since the 5.8 release.

The Slicer extensions manager enables Slicer users to install more than 190 extensions written and contributed by their peers from around the world.

New

  • AnatomyCarve: Allows interactive visualization of 3D medical images by enabling users to perform clipping on segments of their choice

  • ASLtoolkit: Applies image processing techniques for Arterial Spin Labeling (ASL) MRI protocols

  • CADSWholeBodyCTSeg: Fully automated segmentation of 167 anatomical structures in CT.

  • ClassAnnotation: Enables the annotation of clinical image datasets generating CSV reports and organized output folders for analysis.

  • DenseCorrespondenceAnalysis: Dense Correspondence Analysis (DeCA) for Surfaces. DeCA integrates biological insights in the form of homologous landmark points with dense surface registration to provide highly detailed shape analysis of smooth and complex structures that are typically challenging to analyze with sparse manual landmarks alone.

  • EVARSim: Slicer extension to simulate positioning of endovascular devices.

  • IGSpineDeformity: Spine deformity analysis from 3D ultrasound imaging.

  • LayerDisplayableManager: An experimental module designed to simplify the integration of new display pipelines in 3D Slicer. It introduces a flexible and extensible framework for managing layered rendering, interaction forwarding, and camera synchronization across multiple pipelines.

  • ModalityConverter: Medical image-to-image (I2I) translation. The ModalityConverter module integrates multiple deep learning models trained for different kind of I2I translation, providing a user-friendly interface.

  • NNInteractive: Efficient segmentation with nnInteractive, a deep learning-based framework for interactive segmentation of 3D images, allowing for fast voxel-wise segmentation using prompts like points, scribbles, bounding boxes, and lasso.

  • RadioembolizationDosimetry: Taranis is an open-source suite of Python modules for voxel-based liver radioembolization dosimetry, developed for use within 3D Slicer. It enables lung shunt fraction estimation, predictive dose planning, and post-treatment quantification using PET or SPECT images.

  • SlicerANTsPy: Makes ANTsPy available in 3D Slicer. The ANTsPy library wraps the image processing framework ANTs in Python. It includes reading and writing of medical images, algorithms for registration, segmentation, statistical learning.

  • SlicerHeadCTDeid: Remove PHI from head CT DICOM metadata, detect and eliminate DICOM images with burned-in text, and strip superficial facial tissue at the air–skin interface to prevent facial feature recognition in 3D reconstructed head CTs.

  • SlicerMultiverSeg: Interactive in-context segmentation with MultiverSeg.

  • SlicerOpenLIFU: Low Intensity Focused Ultrasound research platform by Openwater.

  • SlicerOrbitSurgerySim: Enables users to interactively register and compare the fit of surgical plates for orbital fracture repair. Users can compare preformed plates with different contours or alternative ways of plate placement.

  • SPECTRecon: Enables the reconstruction of raw SPECT projection data, providing customizable options for image modeling and image reconstruction. The module has a SIMIND to DICOM converter to permit reconstruction of SIMIND Monte Carlo data.

  • UpperAirwaySegmentator: Fully automatic segmentation of the upper airway (nasal cavity, nasopharynx, and oropharynx) on CT and CBCT volumes.

Updated

All the existing extensions have been maintained and updated to account for API and build environment changes.
