Outline of Final Research Achievements

We have developed a superimposed image-guided surgery system which extends the conventional system by a function that enables three-dimensional instant and subjective recognition of the patient’s nose and sinus cavities. We have operated several cases with this system. The superimposed image guidance helped to subjectively recognize location of pathological lesions together with surrounding anatomical hazardous areas.
We improved the precision of the superimposed-image guided navigation system up to about 1 mm. The registration way was made the touch system. It was improved so that an improper registration point might be eliminated automatically.
It was difficult to have an in-built dual-CCD camera for the 70-degree endoscope. Therefore it was difficult to develop of the 70-degree stereoscopic endoscope. We're planning to be continuing developing a 70-degree stereoscopic endoscope.
