AUGMENTED REALITY FOR SURGICAL NAVIGATION
Daegu Gyeongbuk Institute of Science and Technology, South Korea
In these days, augmented reality (AR) has become a key technology for surgical navigation. Using the AR technology, the shape of invisible organs are overlapped to the visible endoscopic or microscopic images. Therefore the surgeon can avoid damaging the healthy tissue, and reduce the incision area. In the AR-based surgery, optical tracker and camera are generally used. Optical tracker can measure the position and pose of multiple markers, and the relationship between the camera and target organs of patient can be measured in real-time by tracking of the markers which are mounted on the camera body and the patient. In the AR display, finding the relationship between the optical marker mounted on the camera body and the center of camera (camera registration) is particulary important. This relationship strongly affects the overall accuracy of AR display. In this talk, the latest AR technologies applied for the surgical navigation are introduced.
