Announcements:Slicer3.2
Introduction
The community of Slicer developers 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:

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. |

Highlights
- Slicer v3.2 - New and Improved Feature Highlights
Complex Visualization Capabilities: Combining cross-sections and 3D surface models tumor, brain morphology, MR angiogram, fMRI and DTI)
Volume Rendering: Fully integrated volume rendering with cropping for easy exploration of volumetric data
Implicit Slice Widget: An interactive tool for specifying oblique views (part of the VTK widget family).
The Lightbox: Functionality for displaying cross-sectional data in columns and rows.
Scenesnapshots allow to capture and recover all parameters of a scene.
Interactive Editor: This new module allows interactive segmentation with robust 2D and 3D algorithms
IO: Improved IO capabilities include support for DICOM, NRRD, NIFTI, Tiff, JPG, Freesurfer, FITS and a number of other formats
Glyphs on corticospinal tract:
New Diffusion Imaging infrastructure includes, dicom import, gradient editor, visualiztion
Remote Data Handling allows uploads and downloads from image informatics frameworks such as BIRN, and XNAT
IGT Toolkit to enable research in Image Guided Therapies
Result of combining affine and b-Spline registration: Robust and fast (parallelized) registration algorithms.
EM Segmenter: A configurable image segmentation tool that uses intensity distributions along with atlas information
Quality Software Process The NA-MIC Kit employs a test-driven software development process. Slicer3 also has a new build process.
Loadable Modules allows developers to provide modules to users outside of the build process, resulting in a smaller installed footprint and greater flexibility to end-users.
