The study for the 3 dimensional measurement by time difference ultra resolution image and for the application to 3 dimensional diagnosis by endoscope.

如今，内窥镜不仅用于诊断，还用于治疗。特别是早期胃癌可以采用内镜下粘膜切除术（EMR）或内镜下粘膜剥离术（ESD）进行治疗。因此，黏膜组织深度方向的病理信息是重要的。超声内窥镜用于粘膜组织深度方向的精确内窥镜诊断。光学相干层析成像（OCT）和共聚焦内窥镜是未来的发展方向。但是图像传感器的发展很快，在一定程度上可以用传统的内窥镜测量粘膜的深度。我们研究了传统内窥镜三维测量的概率。然而，如果常规内窥镜可以拍摄高质量的图像，则可以对胃粘膜表面进行三维测量。就三维测量的准确性而言，并不期望支持系统对粘膜组织诊断的改善。我们认为用立体匹配的方法来实现导航系统是可能的。

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.
