Computer assisted surgery

• Goal
• Use computer vision techniques to plan and guide
  surgical interventions, by giving the surgeon the
  ability to sense critical information that is not
  normally visible to her
• How?
• Capture models of patient anatomy and function
• Use to guide surgeons actions
