The National Alliance of Medical Image Computing, NA-MIC, a NIH National Center of Biomedical Computing, is proud to announce the release of Slicer 3.2. This effort is the culmination of hundreds of person years and tens of millions of dollars of effort [1]. Slicer leverages state of the art open-source toolkits for visualization, medical image analysis, software process, and other tools for processing and accessing data (for more information see the description of the NA-MIC Kit). Slicer offers these capabilities as part of the open-source framework known as the NA-MIC Kit, which facilitates on-going research in biomedical computing, supports commercialization through NA-MIC Kit components, and provides a spectrum of capabilities suitable for researchers with varying levels of computer skills.

Slicer 3.2 is a general purpose biomedical computing application with extensive built-in visualization and analysis capabilities, accessible through an easy to use graphical interface. For advanced users, Slicer may be extended at run-time with user-defined plug-in modules. Release candidates for this application will be available the first week of June 2008. This new release contains hundreds of changes to the software. Highlights include:

  • Improved multi-platform support and availability of pre-compiled binaries for Windows, Mac OS X, and Linux
  • New ways to display, interact and record complex visualizations of cross-sectional and deried data
  • Advanced data fusion and registration capabilities
  • Segmentation tools
  • Support for complex data such as DTI
  • Interfaces to informatics frameworks

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 Slicer3 are not fully tested.
