Auxiliary diagnosis and measurement method and system in endoscopic retrograde cholangiopancreatography

Abstract

The invention discloses an auxiliary diagnosis and measurement method in endoscopic retrograde cholangiopancreatography. The method comprises the following steps: S1, obtaining a perspective image inendoscopic retrograde cholangiopancreatography; s2, inputting the perspective image into a trained joint segmentation model, and carrying out segmenting to obtain a bile duct and a calculus; s3, measuring the width of the lower section of the bile duct and the width of the calculus by adopting a transverse diameter measurement method based on geometric modeling; s4, inputting the perspective imageinto a pre-trained bile duct narrow segment segmentation model, and segmenting a narrow segment of the common bile duct; and S5, measuring the length of the narrow section and the length from the narrow section to the tail end of the common bile duct. According to the invention, the joint segmentation model is established through a neural network to identify bile ducts and calculi; the narrow section of the common bile duct is segmented through the bile duct narrow section segmentation model, then the size of bile duct calculi, the width of the lower section of the bile duct, the length of the bile duct narrow section and the length from the bile duct narrow section to the bile duct tail end are measured, and a doctor can be assisted in diagnosing the bile duct calculi and bile duct narrowness through the measurement result.

Description

technical field [0001] The invention belongs to the technical field of medical image processing, and relates to an auxiliary diagnosis and measurement system and method in endoscopic retrograde cholangiopancreatography, in particular to an image segmentation technology based on deep learning in endoscopic retrograde cholangiopancreatography Assisted diagnosis and measurement system and method. Background technique [0002] Choledocholithiasis is a common digestive system disease, which can easily cause complications such as pancreatitis, cholecystitis, and cholangitis, and can be life-threatening in severe cases. Common bile duct stricture is also one of the common biliary system diseases, and endoscopic stent placement and drainage is a common minimally invasive diagnosis and treatment method. Endoscopic retrograde cholangiopancreatography is a common method for the diagnosis and treatment of common bile duct stones and strictures. Due to its many complications and high te...
