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 LandmarkRegistration 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 non-linear transforms in the module
  • Display of transform information
  • Transform visualization
• 

  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.

  • vtkEventBroker performance improvement
  • Optimized qMRMLSceneModel::nodeIndex performance
  • Optimized performance of observations management in vtkMRMLScene

• Reduce memory footprint
  • Fix memory leaks

• Reduce installer size

• Faster image stack (png, jpg, bmp, tiff...) loading

Markups

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

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

• Bundle pydicom python module in Slicer package

• Add helper methods to ScriptedLoadableModuleLogic for managing parameter nodes

• SelfTest: Add clickAndDrag() method to the scripted module. It allows to send synthetic mouse events to the specified widget (qMRMLSliceWidget or qMRMLThreeDView)

• Improve slicer.util python module.
  • 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.

• Markups: Add an event PointEndInteractionEvent for the end of a fiducial interaction

• TODO: Add reference to VTKv6 blog posts

Other

• Improved integration of non rigid deformations
• mrb files

• Improved CLI AutoRun ensuring slice view is not reset when inputs are updated.

For Developers

Under the hood

• VolumeLogic:
  • Add method ResampleVolumeToReferenceVolume
  • Add method CloneVolumeWithoutImageData

• 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
  • Add option Slicer_ITKV3_COMPATIBILITY. This option enabled by default will allow (if disabled) to build Slicer with ITKv3 compatibility later disabled and ITK_USE_64BITS_IDS enabled.
