Abstract

The invention discloses a microvascular distortion degree quantification method for gastric mucosa dyeing amplification imaging. The method comprises an image segmentation method, a blood vessel center line extraction method and a surface density method. The image segmentation method is used for extracting a clear area and a microvessel whole image in the gastroscope image; the blood vessel center line extraction method is used for extracting the center line of each microvessel and calculating the perimeter of the microvessel corresponding to a pixel point on the center line; according to the surface density method, calculating the surface density by projecting the perimeter of the microvessel to the minimum circumscribed cubic surface of the microvessel; and finally, weighting the surface densities of different surfaces of the minimum microvessel circumscribed cube to obtain a microvessel distortion degree coefficient, and then judging the microvessel distortion degree grade according to the distortion degree coefficient.

Description

technical field [0001] The invention relates to the technical field of image processing in the medical field, in particular to a method for quantifying the twisting degree of microvessels in gastric mucosa staining and magnification imaging. Background technique [0002] Gastric cancer is the fifth most common cancer in the world, and it is the third leading cause of cancer death. The five-year survival rate of advanced gastric cancer is only 30%, while the five-year survival rate of early gastric cancer is as high as 90%. The advent of chromoendoscopy established the endoscopic diagnosis method for early gastric cancer. The combined application of magnifying gastroscopy and electronic chromoendoscopy can observe the tiny blood vessel structure and the fine structure of mucosal surface that cannot be observed by ordinary gastroscopy, which provides conditions for endoscopic diagnosis of early gastric cancer. Vascular dysmorphia is an important condition for the diagnosis o...
