Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

We plan the study to explore the application of endoscopic laser speckle imaging and multispectral blood oxygen imaging to observe gastrointestinal lesions, as well as the differences in the morphology, density and functional status of mucosal surfaces and deep blood vessels of different gastrointestinal lesions, also to explore the role of endoscopic multimodal functional imaging in common gastrointestinal diseases, especially in the early diagnosis of gastrointestinal tumors.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The current focus of electronic endoscopy is on the morphology and fine structure of the mucosal surface, and there is no effective observation method for the deep structure of the mucosa and the function of blood oxygen binding. However, the multilayer morphology and functions of mucosal vessels under different conditions of digestive tract lesions should be different. Therefore, we propose a method of endoscopic multimodal functional imaging to the conventional endoscopic examinations observing the mucosa of the digestive tract, which is based on the existing electronic endoscope, laser speckle contrast imaging and multispectral blood oxygen imaging technology. Laser irradiation was given to obtain the information of coherent light on the mucosal surface and deep scattering of coherent light to obtain multi-level vascular distribution information, and multispectral irradiation imaging was carried out to obtain the oxygenation situation of the mucosa. Finally, we may find the differences of images of deep blood vessels among common gastrointestinal diseases, which could help us to make early diagnosis of gastrointestinal tumors noninvasively.
