Abstract

The invention discloses a digestive endoscopy navigation method and system. The method comprises the following steps: fusing key points of two frames of images, and performing offline marking by utilizing displacement vector distribution of the fused image to obtain a truth value of training data; building a twin neural network to carry out supervised pre-training; and estimating the position coordinate of the next frame of the lens of the digestive endoscopy by utilizing the displacement vector distribution output by the trained model, and further outputting a complete movement track to realize the navigation of the digestive endoscopy. The self pose and the motion direction of the digestive endoscope can be accurately recognized, the motion track is grasped on the whole, and the adaptability is high.

Description

technical field [0001] The present invention relates to the technical field of medical image processing, and more particularly, to a digestive endoscope navigation method and system. Background technique [0002] Colonoscopy is one of the important means for the diagnosis of malignant tumors in anorectal surgery. The doctor controls the insertion of the colonoscope from the patient's anus. The inspection is divided into two stages: forward and backward. In the previous stage, the doctor uses the clinical experience and the image of the colonoscope to find the cavity and advance the lens , until it reaches the tail of the cecum, and then proceed to the regression stage to observe whether there are polyps or other lesions in the intestine. In this traditional colonoscopic operation, doctors only rely on endoscopic imaging and their own experience to find the advancing lens in the center of the lumen. Correctly judging the moving direction of the lens will eventually lead to t...
