Transform node in a MRML scene.



Key Investigators

  • GE Research: Jim Miller, Bess Lee
  • Isomics: Steve Pieper, Alex Y.


Objective

Extend Slicer's suite of transformations to include nonlinear transformations (B-spline, deformation grids) in the MRML scene, visualization pipeline, and command line modules.


Approach, Plan

  • Develop new MRML nodes and MRML storage nodes for B-splines and deformation grids.
    • vtkITK wrapper around ITK classes
  • Add attribute to transform nodes to indicate whether they represent a "Transform to World/Parent" or "Transform from World/Parent"
  • Extend visualization system for "Transform to World/Parent" or "Transform from World/Parent"
  • Extend command line modules to annotate a transformation as a "Transform to World/Parent" or "Transform from World/Parent"

Progress

  • MRML nodes and storage nodes for B-spline and deformation grids done.
