| Outline of Final Research Achievements |
In this study, we aimed to explore sparse modeling to estimate organ deformation and mechanical characteristics in real time from limited visual information during endoscopic surgery and robot surgery. We have developed a method to estimate organ deformation by using elastic body model constructed from three-dimensional CT / MRI image as prior knowledge and extracting highly robust multi-dimensional feature values from endoscopic images. We designed a prototype surgical support system that achieves real-time visualization of tumor position in response to organ deformation and resection, and evaluated the prototype system by applying patient data assuming clinical application.
