  1. Non-rigid MR-Ultrasound Registration for Neurosurgery, Prostate MRgFUS, and Brachytherapy Matthew Toews ,Sandy Wells, Steve Haker,Tina Kapur, Nathan McDannold, Ben Schwartz, Michel Audette IGT Project Week December 8-12, 2008

  2. 2) Improve intra-procedural visualization and guidance using imagery 3) Registration: fuse pre- and intra-procedural imagery 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
