Project Description

Steered image registration in Slicer using intelligent interaction rather than direct interaction where user specifies deformation changes.


  • Develop interaction schemes that allows users to indicate incorrect regions
  • Provide intelligent interfaces so users provide minimal interaction without detailed control of image deformations

Approach, Plan

  • Investigate data exploration techniques for highlighting rotational errors
  • Implement efficient, responsive extensions using the Slicer 4 Python extension platform and PyOpenCL


  • Testing the use of robust PCA for providing hints on rotational misalignment
  • Investigating the modeling of appropriate correction steps given the possible misalignments
