Registration

• Overview:
  • The Register Images module is an integrated solution to all your registration needs, if you want to have a resampled volume as output. It provides access to rigid, affine and b-spline itk technologies.
  • The Transforms Module allows to manually align two volumes. This can be used for initial alignment.
  • Linear, affine and Deformable B-Spline modules can be used stand-alone or one after the other. They can accept transformation matrices as the start pose and produce either transforms or resampled volumes as output.
  • Transformation matrices derived from these modules can be used as input for resampling other volumes (including DTI) using the Resample Volume 2 module.

Extensions for Downloading

Slicer on NITRC

Work is in progress to create infrastructure for searching and loading extensions. See Slicer3:Extensions for more information.

• This will allow contributors and software developers to post their own Slicer extensions and have them compiled against the "official" versions of Slicer.
• Users can browse these contributed extensions and install them on their own versions of Slicer.

We are currently using NITRC as a repository for contributed extensions. As a general rule, we do not test them ourselves, it is the downloaders job to ensure that they do what they want them to do. Click here to see a listing of Slicer 3 extensions on NITRC.

XNAT Desktop and FetchMI

• Work is underway to use XNAT desktop (xnd) as a local database for Slicer. This database will exist in parallel with the other load and save mechanisms and will allow to download/upload individual files or entire scenes with all their dependent files.
• Users of Slicer will have to install xnd on their computer. Once set up, the FetchMI interface will allow users to upload and download mrml scenes with all the dependent files, or individual volumes, models, other components of slicer scenes.
• See here for a link to the download site for xnd. See here for documentation on how to install XNAT desktop on your computer.
• On Macs and Linux you currently have to change permissions of the executable after installation.
• In the future (summer 2009) xnd will be able to upload and download mrml scenes to xnat enterprise.

• FetchMI is the current interface inside slicer for exploring information stored in xnd and down and upload such data. It is a "sandbox" implementation to help us understand how users will want to use remotely stored data and metadata in the Slicer environment. Eventually, FetchMI's remote load and save will be integrated with Slicer's existing load and save interfaces, and FetchMI's data tagging functionality will be more fully developed as a new metadata authoring module.
• See here for more information about FETCHMI. User comments and suggestions are welcome.

FreeSufer Integration

• FreeSurfer surfaces and scalar overlays can be loaded via the Models module and MGZ volumes can be loaded via the File -> Add Data widget.
• More detailed information can be found here.

Requirements for modules to be added to the release

The module is feature complete for the tasks advertised on 2-4-2009 The module has a test. See here for more information. Module has documentation on the Slicer wiki. Please use the template provided here to structure your page. Please add a pointer to the documentation on the Slicer wiki to the the Help tab of the module. See the Editor module in Slicer for an example. The contributor (and their manager/advisor), the lab (with labs/institution logo) and the funding source (with grant number, logo optional) are listed in the Acknowledgment tab of the module. Please see the Models module for and example. The people listed in the acknowledgement will be the primary people for support and maintenance relative of the module. Style Guide: All acknowledgment icons should be 100x100 pixels, preferably in png format. Accessing logos: Icons for BIRN, NAC, NA-MIC and IGT are included in Slicer3/Base/GUI//vtkSlicerBaseAcknowledgementLogoIcons.cxx/h and resources for them are in Slicer3/Base/GUI/Resources/vtkSlicerBaseAcknowledgementLogos_ImageData.h. The API for vtkSlicerModuleGUI provides access to these icons. Adding logos: Please add additional image resources and logo icons to these files as required in order to promote shared use (and to prevent duplication in the code.) If your module has documentation in Slicer 3.2, please copy/paste/update into the 3.4 version
