Summary What is 3D Slicer Slicer Nightly Highlights Slicer Extensions Other Improvements, Additions & Documentation

Summary

The community of Slicer developers is proud to announce the release of Slicer Nightly.

  • Slicer Nightly introduces
    • an improved App store, known as the extension manager, for adding capabilities to Slicer. More than 50 plug-ins are currently available.
    • close to 400 feature improvements and bug fixes lead to improved performance and stability.
    • augmentation of many modules.
  • Click here to download Slicer Nightly for different platforms and find pointers to the source code, mailing lists and bug tracker.
  • Please note that Slicer continues to be a research package and is not intended for clinical use. Testing of functionality is an ongoing activity with high priority, however, some features of Slicer are not fully tested.
  • The Slicer Training page provides a series of courses for learning how to use Slicer. The portfolio contains self-guided presentation and sample data sets.

The main slicer.org pages provide a guided tour to the application, training materials, and the development community. New users should start there because we try to keep the pages organized and up to date.

What is 3D Slicer

Slicer is a community platform created for the purpose of subject specific image analysis and visualization.

  • Multi-modality imaging including, MRI, CT, US, nuclear medicine, and microscopy
  • Multi organ from head to toe
  • Bidirectional interface for devices
  • Expandable and interfaced to multiple toolkits

There is no restriction on use, but permissions and compliance with rules are responsibility of users. For details on the license see here

Slicer Nightly Highlights

  • New and Improved Modules

  • New Slice View Annotations is now available in DataProbe module. This new feature includes information about volume nodes of different layers of slice view in the form of corner text annotations (including DICOM information if available), color scalar bar and an interactive scaling ruler.

  • New LandmarkRegistration module providing interactive registration and inspection.

  • New Subject hierarchy module organizes and handles loaded data, providing processing and analysis features through plugins.

  • Improved Transforms module with support for non-linear transforms, visualization of transforms in 2D and 3D, detailed transform properties view - click here for demo video.

  • New ExtensionsWizard tool deprecating the ModuleWizard.
    • This new tool separates the concepts of extensions and modules, and allows creating an extension containing several modules, as well as adding modules to an existing extension.
    • It allows to publish an extension source code to github.
    • It provides an easy way to create a pull request on the extension index.

  • New Compare Volumes supports an overview of one or more volumes in the scene.

  • DICOM module user interface is improved for a better user experience. DICOM meta-data (header) viewer is now available and auto-examine in the DICOM browser makes it easier to work with plugins.

  • All application error and warning messages are saved to file. Logged messages for the current and recent sessions are available from the new error report box (menu: Help / Report a bug).

  • Scene Views module GUI updated with better layout.

  • Markups module fiducial right click menu expanded to include copy and showing RAS coordinates. Show Slice Intersections check box added.

  • Colors module expanded to support continuous color maps, added an option to use the color names as labels on the scalar bar.

DICOM

  • Improved DICOM support and user experience
    • Added a way to change the table densities in three levels: compact, cozy and comfortable.
    • Re-arranged the patient, study and series search box so that the search box will be on the top of tables for both horizontal and vertical cases.
    • Resize tables based on contents.
    • Allow users to acknowledge all DICOM loading errors with a single click
    • Add DICOM meta-data (header) viewer
    • Auto-examine in dicom browser added by providing two modes: Advanced and Non-advanced mode.
    • Added repair tool for DICOM database

Transforms

  • Improved integration of non rigid deformations, including grid (displacement field) and bspline transforms
  • Interactive application of non rigid deformations to volume slices, models, markups
  • Visualization of any transforms as glyphs, grid, or contours in 2D slice and 3D views - click here for demo video
  • Computing and applying inverse transforms, compositing any number of transforms
  • Real-time update: if the transform (or any visualization parameter) is changed then the visualization is updated immediately (interactive visualization while editing the transform)
  • Detailed transform information display (type of transform, basic properties, displacement at current position)
  • Loading/saving of oriented bspline transforms with or without additive bulk component
  • Loading/saving of oriented grid transforms
  • Loading/saving of transforms in h5 file format

Colors

  • Improved Colors module user interface
    • Added support to display continuous color scales
    • Added an option to use color names as labels on the scalar bar

Markups

  • Improved Markups module user interface
    • Add slice intersections toggle
    • Add right click option to copy markups list
    • Add coordinates to right click menu

Editor

  • Add a Sphere option to the PaintEffect to make it quicker to segment large anatomical regions that are somewhat spherical.
  • Paint using pixel mode if brush size is too small
  • Button effect are checked/unchecked based on the 'effect' property stored in the parameter node

Extensions Manager

  • Add search box
  • Add 'More' link
  • Load extension icon from disk
  • Implement downloading of extension icons
  • Install extension dependencies
  • Add mechanism to check for extensions updates

Slicer Extensions

TODO: Will be generating automatically list.

  • New and Improved Extensions
  • Foo.png

    Foo for doing awesome stuff.  NEW

Other Improvements, Additions & Documentation

Optimization

  • Improve Rendering pipeline performance optimizing observations management
  • Reduce memory footprint (Fix memory leaks)
  • Reduce installer size
  • Faster image stack (png, jpg, bmp, tiff...) loading

Rendering / Visualization

  • Add Multi-sampling option
  • Improved scalar bar to allow displaying of annotations in conjunction with labels.
  • Slice Annotations: enhance the DataProbe module providing an easy way to show/hide/customize corner annotations, ruler and color bar in the Slice viewers.

CLI / SlicerExecutionModel

  • Improved CLI AutoRun ensuring slice view is not reset when inputs are updated.
  • In developer mode do not remove CLI input and output files
  • Reduce the chance of crashes when CLI returns result images

Python scripting

  • Add support for real Qt resources in Python. See r23290 for details.
  • Improve VTK event support adding a way to specify the CallData type. See here for details.
  • Bundle pydicom python module in Slicer package
  • Add helper methods to ScriptedLoadableModuleLogic for managing parameter nodes

    • Add modulePath(moduleName) method
    • Add resetThreeDViews/resetSliceViews
    • Add VTKObservationMixin
    • Add getFirstNodeByClassAndName()
    • Add NodeModify context manager: It allows to easily disable modified event associated with a node, and automatically re-enable them and invoking them if it applies.

Other

  • Help / Report a bug: Application error/warning/debug log messages are now saved to file. Added option to copy/paste log file contents of recent Slicer sessions to bug reports.


  • TODO - Please add entry to illustrate awesome feature listed above

For Developers

Under the hood

  • Add support for user-defined stereo-viewing options
  • Build-system
    • Improve support for Visual Studio 2013
    • Refactor management of external project launcher settings. See r23724
