Outline of Final Research Achievements

In order to support liver surgery, we have developed technologies for 1) pre-operative planning using three-dimensional(3D) CT images, and 2) navigation exploiting Augmented-Reality (AR) where information from computers can be super-imposed onto real scene. In the conventional pre-operative planning, surgeons determine the resected region based on their empirical knowledge. To solve this problem, we have developed a method that finds the optimal resected region based on the geometrical relation between a tumor and liver vessels under the condition of patient’s liver function. This approach allows both of reducing the resected volume and preventing tumor metastasizing.
Moreover, a navigation system has been developed using a see-through-type head-mount display that super-impose the 3-D content onto the patient’s abdomen, and a touch-less user interface to manipulate the 3-D content.
