  1. Non-Rigid Registration on SPIE 2002 First Part: TPS

  2. List of related papers • <Three-dimensional warping registration of the pelvis and prostate> • <Nonrigid mammogram registration using mutual information> • <Shape-adapted motion model based on thin-plate splines and point clustering for point ser registration>

  3. Warping Registration Three-dimensional warping registration of the pelvis and prostate Baowei Fei, Corey Kemper,David L Wilson Case Western Reserve University University Hospitals of Cleveland

  4. Warping Registration • Automatic rigid body registration to get global transformation • Local warping registration Object: Pelvis MR image

  5. Warping Registration • Similarity measurements Mutual Information Correlation Coefficient

  6. Warping Registration • Rigid Body Registration with Special Features Multi-resolution approach Low Resolution:CC Simplex Full Resolution:MI Restart: local maximum

  7. Warping Registration • Control Point selection Manual • Control Point optimization Volume of Interest Simplex VOI • TPS warping 3-D TPS transformation

  8. Warping Registration • Experiments Control Point Selection: 180 • Comparison Warping & Rigid registration • Condition of robust CC & MI restarting mechanism

  9. Mammogram registration Nonrigid mammogram registration using mutual information Michael A.Wirth, Jay Narhan, Derek Gray University of Guelph

  10. Mammogram registration • Object: Mammogram Images • Comparative Analysis--- mammograms are inspected for characteristic signs of potential cancer through the comparison of various analogous bilateral or temporal mammograms

  11. Mammogram registration • Mammogram from MIAS digital mammogram database. • Website http://www.wiau.man.ac.uk/services/MIAS/MIASweb.html

  12. Mammogram registraion • Deformable behavior of breast acquisition process: 3D positioning of the breast, amount and geometry of compression applied to it. Breast is deformable, mobile, soft-tissue structure

  13. Mammogram Registration • Mutual Information • Thin-Plate Splines n Control Points

  14. Mammogram registration • Hierarchical registration algorithm Global Registration Localized (rigid) sub-image registration Nonrigid registration TPS Registered mammograms Displacement vector field

  15. Motion model Based Shape-adapted motion model based on thin-plate splines and point clustering for point ser registration Julian Mattes, Hohannes Fieres, R.Eils German Cancer Research Center

  16. Motion Model Based • Registration Cost functional Optimization strategy The specification of deformation---- Motion Model

  17. Motion model based • Landmarks are placed to adapt to the shape • DOF • Best-fitting deformation with minimal DOF

  18. Motion model based • Distance Cluster Method • Octree Method • Annealing Method
