Computer assisted surgery
• Goal:• 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 surgeon’s actions
