Slicer 4.0 contains a new graphical user interface (built using the Qt toolkit), a refactoring of the Slicer core that touched nearly every line of the code base, a new layout manager, a simplified Python interface, and numerous other noteworthy additions and enhancements.  A detailed
list of improvements can be found on the Slicer wiki, along with additional documentation for Slicer 4.0.

Developed in collaboration with the National Association for Medical Image Computing (NA-MIC) and the broader Slicer community, Slicer 4.0 is an open-source (BSD-style license) platform for medical image segmentation, registration, visualization, and analysis. It represents a practical integration of innovations from a multitude of fields, including medical image analysis, cross-platform software development, collaborative software development, and extensible platform design. Kitware employees and products are at the heart of many of these innovations.
