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

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.

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

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
