Power Apps

New stand alone SCIRun Power Apps! These applications hide the complexities of the powerful SCIRun dataflow interface, allowing the user to focus on a specific task. Currently there are two Power Apps. BioTensor and BioFEM.

• BioTensor is used for doing Diffusion Tensor Imaging. This application takes the user from data acquisition, through registration and building diffusion tensors. In addition, several visualization techniques such as Planes, Isosurfaces, Glyphs and Fibers are provided to allow the user to investigate the data.
• BioFEM is an encapsulation of the forward-fem network that is included in the BioPSE package and described in the BioPSE Tutorial. With BioFEM, the user can run finite element bioelectric field simulations based on volume conductor models and dipolar sources, and can interactively visualize the simulation results with electric field streamlines and isopotential surfaces.

New Projects

• Support for the NLM Insight Segmentation and Registration Toolkit (www.itk.org)! Many Insight Filters are wrapped with SCIRun modules. SCIRun infrastructure updated to easily allow wrapping of new filters. See Chapter 8 of the Users Guide on how to use ITK Filters. For source distributions, Insight must be installed separately. See the installation guide on how to install Insight. The RPM distribution includes Insight.
• Upgraded the Network Editor to be much more user friendly. See "Network Editor" below (and Chapter 5 of the Users Guide).
• Full support of OSX (See installation guide).

Data Sets

• New "insight" directory with sample data for Insight nets.
• New "brain-dt" directory with sample data for the BioTensor Power App.

Network Editor Enhancements

The SCIRun Dataflow Network Editor has been reworked to make use much easier. New features include the ability to select multiple modules and group them. These grouped modules can be merged into a Sub-Network (also known as a Macro Module) allowing for the ability to more easily deal with complex networks. Modules and pipes can now be disabled to temporarily turn off parts of comlex networks. Pipes and modules can be annotated on the Network Editor canvas to help make the dataflow layout easier to understand. A basic undo feature has been added allowing the user to undo/redo the creation/deletion of pipe connections. Tool tips have been added to may widgets.
