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

在这些日子里，内窥镜被应用于治疗以及诊断。特别是早期胃癌，可以通过内镜下黏膜切除术（EMR）或内镜下黏膜下剥离术（ESD）进行治疗。因此，粘膜组织的深度方向的病理信息是重要的。对于粘膜组织的深度方向的精确内窥镜诊断，使用超声内窥镜。光学相干层析成像（OCT）和共焦内窥镜将是未来的发展方向。然而图像传感器的发展非常迅速，它可以在一定程度上测量粘膜的深度与传统的内窥镜。我们研究了用传统内窥镜进行三维测量的可能性，然而，如果用传统内窥镜可以拍摄高质量的图像，则可以进行胃粘膜表面的三维测量。就三维测量的准确性而言，不期望用于粘膜组织诊断的支持系统的改进。我们认为，立体匹配方法有可能成为一种导航系统。

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.
