| Outline of Final Research Achievements |
First, we investigated the appropriate conditions for creating the high-resolution multi fused three-dimensional computer graphics (3DCG). In this study, we discovered that narrowing the image data bounding box to the region of interest improves the accuracy of registration between different modalities or different images. This result helped us to create the high-resolution 3DCG images that depict brain tissue with the same accuracy as the actual operative field.
Second, we developed a microscopic optically tracking navigation system that uses high-resolution multi-fused 3DCG. Our navigation system consists of three components: the operative microscope, registration, and the image display system. In this study, we showed that the 3D CG image displayed on the monitor of this system corresponded well with the operative scene under the microscope. This system may reduce intraoperative complications because it will enable surgeons to intuitively comprehend the 3D operative anatomy.
