Goals
1) Improve clinical outcome
3
Imagery

• Pre-procedural MR
• High image quality
• Procedure planning

• Intra-procedural US
• Low image quality
• Cheap, portable

4
Registration
Compute a spatial mapping between pre-procedural
MR and intra-procedural US images
5
Research Challenges

• Geometrical relationship
• Tissue deformation, resection
• Intensity relationship
• Multi-modal, non-stationary
• General solution
• Minimal customization

6
Plan Non-rigid MR-US Registration

• Definition of relevant research issues
• Visual Inspection of data sets brought by
  participants
• Discussion of clinical requirements for the three
  applications Neurosurgery, Prostate MRgFUS, and
  Prostate Brachytherapy
• Where available, identification of particular
  algorithms or commercial products for each of the
  focus applicatons
