Summary
The community of 3D Slicer developers is proud to announce that version 5.6 is now available for download. This release includes support for 3D Segmentation rendering speedup, interactive thick slab reconstruction (TSR), enhanced Endoscopy flythrough and improved support for DICOM regularization transform hardening. It also includes enhancements across core modules and introduces over 5 new extensions, each bringing additional features and improvements.
3D Slicer 5.6 builds on the success of earlier versions that have had over 1.4 million downloads of the core application and 6.8 million downloads of extensions during the last decade.
The development of 3D Slicer—including its numerous modules, extensions, datasets, pull requests, patches, issues reports, suggestions—is made possible by users, developers, contributors and commercial partners around the world. 3D Slicer is based on a stack of open-source software and we are working constantly on updating the underlying packages. This development is funded by various grants and agencies. For more details, please see the 3D Slicer Acknowledgments page.

slicer.org serves as the central hub for the application, training materials, and the development community, offering a series of tutorials and data sets through the Slicer Tutorials page.
Please note that Slicer continues to be a research package and is not intended for clinical use (clinical users must obtain the necessary ethics or regulatory approvals).
Highlights
-
New Extensions: 10+ new and improved extensions, including several AI segmentation tools, such as fully automatic segmentation of 100+ structures in CT images in less than 2-minutes using TotalSegmentator v2, improved volume rendering of RGBA image volume, tools for liver intervention planning, review and annotation of multi-parametric imaging datasets, and support for exploring and accessing imaging data available from the NCI Imaging Data Commons.
-
3D Segmentation Rendering speedup: The Surface Nets algorithm provides a ~7x speedup to the generation of surface models from segmentations compared to the default Flying Edges method.
-
Interactive Thick Slab Reconstruction (TSR): It can now be enabled and modified from the slice controllers and slice views.
-
Enhanced Endoscopy Flythrough: Support flying through a path along with adjusting and saving camera at specific position.
-
Simplified Image Capture: Simplified single-image capture in ScreenCapture module.
-
Transform Hardening Support in DICOM Scalar plugin: Identified sub-series (each loaded as independent volume node) now support being grouped by orientation with hardening of the regularization transform hardening. This can be enabled in the DICOM settings by selecting harden regularization transform instead of the default apply regularization transform.
-
Security Enhancement: Added security policy describing how to report security vulnerabilities along with details about the preferred languages, supported versions and scope.
This version was released on November 27th, 2023, and the associated git tag is v5.6.0. Information about previous releases can be found on the Release Details page.
