| Research Abstract |
In these days, an endoscope is applied to therapy as well as a diagnosis. Especially, the early gastric cancer can be treated by either Endoscopic Mucosa Resection (EMR) or Endoscopic Submucosal Dissection (ESD). So a pathological information of a depth direction of mucosal tissue is important. For a precise endoscopic diagnosis of a depth direction of mucosal tissue is used by ultrasound endoscope. And Optical Coherence Tomography (OCT) and confocal endoscope will be used in the future. However the development of an image sensor is very fast, it could measure the depths of mucosa with a conventional endoscope to some extent. We studied about the probability of three dimensional measurement with a conventional endoscope.
However, a three dimensional measurement of gastric mucosa surface can be done, if a highly quality image can be taken by a conventional endoscope. As far as accuracy of 3 dimensional measurement, it is not expected that the improvement of support system for the mucosa tissue diagnosis. We think that it is possible to be a navigation system by the stereo matching method.
