Objective
We are developing tools and enhancements to ITK and Slicer in order to adapt Slicer to be a tool that is useful for the visualization of astronomical data, specifically spectral line data cubes for now.
Approach, Plan
Our approach is summarized on the Astronomical Medicine web site. The main challenge to this approach at the moment, is the impedance mismatch between celestial coordinates and medical imaging coordinates, and a lack of infrastructure within ITK and Slicer to allow for alternative coordinate systems.
Our plan for the project week is to see if we can add support for World Coordinate System grid images to Slicer3 in order to allow astronomical coordinate readout from slice planes.
Progress
We have implemented software that has allowed Slicer to be used as a platform for doing cutting-edge radio astronomy. Peer-reviewed publications are pending, including one in Nature.
At 2008 Summer Project Week
- Learned about how we can use the new Loadable Modules feature to help solve our problem.
- Worked with Luis to make itk::Transform<>::GetInverse() virtual.
- Learned that another group is working on adding support for grid transform MRML storage and transform nodes, so assuming that this pans out, we need to figure out how to add support for using these from the SliceSWidget.
