| Outline of Final Research Achievements |
We have developed a mapping system of endoscopic views on a 3D placenta model constructed from ultrasound images for Fetus surgery. The system does not require external trackers. The relative position between the endoscope and the 3D model was measured by 3D ultrasound and moving distance of endoscope during surgery was estimated by feature matching of endoscopic image. Using these relative position information and moving information endoscopic views were overlaid onto the surface of the model. This addresses operational challenges including the limited field-of-view and the lack of 3D perspective associated with minimally invasive procedure. Experimental results show that The R.M.S. error of the image mapping of 20 frames was 1.1 mm. The feasibility of the framework is also demonstrated through. We have also developed contrast enhance system between vasculature and placenta by using narrow band images.
