Coloscope image evaluation method and system based on OfficientNet structure

Abstract

The invention relates to a colonoscope image evaluation method based on an OfficientNet structure, and the method comprises the following steps: S1, obtaining a colorectum sequence image, and preliminarily classifying the colorectum sequence image into three segments of sub-sequence images of a left half colon, a transverse colon and a right half colon; s2, preprocessing the sub-sequence image; step S3, according to the preprocessed sub-sequence images, based on a scalable OfficientNet network model, obtaining an optimal classification; and S4, based on a BBPS intestinal tract preparation evaluation standard, respectively scoring the three segments of sub-sequence images of the left half colon, the transverse colon and the right half colon, accumulating the score of the image with the worst intestinal tract cleanliness of each segment, and further evaluating whether the colonoscope image is qualified or not. According to the invention, automatic and accurate evaluation of intestinal preparation is effectively realized, and the burden of doctors can be greatly reduced.

Description

technical field [0001] The invention relates to the field of image pattern recognition and classification, in particular to a colonoscope image evaluation method and system based on an EfficientNet structure. Background technique [0002] Before the colonoscopy operation, the colorectal tract is cleaned of feces and digestive residues, and the cleaning process of emptying foreign objects in the intestine is called bowel preparation. Bowel preparation is an important prerequisite for a successful colonoscopy. At present, the method of stopping food in advance before colonoscopy combined with oral intestinal cleanser is usually used to clean the bowel. However, there are related domestic literature reports that the rate of insufficient intestinal preparation in outpatients is 12%-25%, and the rate of insufficient intestinal preparation in elderly patients is even higher, ranging from 17% to 32%. It has also been reported in foreign literature that the incidence of insufficie...

However, there are relevant domestic literature reports that the rate of insufficient intestinal preparation in outpatients is 12%-25%, and the rate of insufficient intestinal preparation in elderly patients is even higher, ranging from 17% to 32%.

It has also been reported abroad that the incidence of insufficient bowel preparation in patients undergoing colonoscopy is 20%-25%.
