Computer Assisted Surgery and Medical Image Analysis

1. Computer Assisted SurgeryandMedical Image Analysis Computer Vision Group Artificial Intelligence Laboratory Massachusetts Institute of Technology Surgical Planning Lab Brigham and Women’s Hospital Harvard Medical School

2. 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 surgeon’s actions

3. Conventional Surgery: See the surface Provided by Nakajima, Atsumi et al.

4. Image Guided Surgery: See under the surface Provided by Leventon et al.

5. Intelligently aiding the surgeon • Convert medical images into models of patient’s: • Structural anatomy • Functional anatomy
