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 implement a mechanism that will allow world coordinate system information to travel through the ITK pipeline via an ITK image's metadata dictionary. If we accomplish this, and there is time left over, then we hope to implement bidirectional procedural transforms to map between voxel coordinates and world coordinates.

Progress

June 2007 Project Week

Worked with Jim Miller to implement preservation of the ITK metadata dictionary through the Slicer pipeline, worked with Luis Ibanez to help implement ITK streaming file I/O, set up more robust dependency rules in our CMake config, and debugged a problem with our use of ITK filters.

Jan 2007 Project Half Week

Solved problem of itk::ImageIOBase being incompatible with CFITSIO's "extended filename syntax", identified compatibility issues present in the most recent version of Slicer 3, and devised a plan for passing FITS WCS transforms around in Slicer by encapsulating them in itk::Transform objects held in an image's metadata dictionary.

June 2006 Project Week

Implemented a prototype FITS reader for ITK. We later released this as an open-source FITS-to-NRRD file converter, which is available here.
