Outline of Final Research Achievements

The ultimate goal of this study is to achieve 'Technical development of virtual thoracoscopy assisted thoracic surgery', and we conducted three basic research studies to achieve this goal. These studies include research on aligning virtual and real images, comparing positions on virtual images with those on a 3D organ model of actual size, and developing a technology that allows viewing of the hole entire chest cavity. There were several bottlenecks that arose for performing all surgical operations using virtual images, such as position identification, consistency, and time lag, and we spent time conducting basic experiments to solve them. As a result, simulation surgery using virtual images and clinical deployment could not be achieved during the research period, and became a future ongoing task. Our aim is to construct a navigation system for "Technical development of virtual thoracoscopy assisted thoracic surgery" by aligning virtual and real images and synthesizing images
