Typing method based on intelligent hepatic portal vein

Abstract

A typing method based on an intelligent hepatic portal vein comprises the steps of establishing a digital liver three-dimensional model, analyzing the blood vessel shape, deformation, distribution and dominating areas of the hepatic portal vein, and automatically determining the type of the hepatic portal vein according to an analysis result, and specifically comprises the steps of establishing a hepatic portal vein digital model, performing three-dimensional reconstruction on the liver, finding the components of the hepatic portal vein in the component library of the three-dimensional model of the liver, and labeling the hepatic portal vein digitally. Compared with the prior art, the digital labeling is performed on the established three-dimensional model in advance, the personalized portal vein can be quickly and intelligently typed, the typing efficiency is improved, the occurrence probability of empirical errors is reduced, and the typing accuracy is improved. Based on the visual three-dimensional graph and portal vein typing, operation planning can be standardized, and the operation plan making efficiency is improved. By typing the hepatic portal vein, accidents in an operation can be effectively prevented, the operation risk is reduced, and the success rate of the operation is improved.

Description

technical field [0001] The invention belongs to the technical field of medical image processing, in particular to a typing method based on intelligent hepatic portal vein. Background technique [0002] At present, before surgical treatment of patients with liver diseases in actual clinical practice, it is necessary to fully grasp the anatomical structure of the hepatic portal vein, the variation of the hepatic portal vein, the morphological characteristics of the right posterior branch of the hepatic portal vein and the distribution of its branches. It is necessary to classify the hepatic portal vein according to the shape and variation of the hepatic portal vein. The classification of the hepatic portal vein provides morphological basis for personalized clinical liver disease surgical treatment and catheter interventional therapy and other applications. [0003] At present, clinicians' understanding and classification of hepatic portal veins are mostly based on CT / MR two-d...

AI Technical Summary

Problems solved by technology

[0003]Currently clinicians’ understanding and classification of hepatic portal vein is mostly based on CT / MR two-dimensional graphics and their own clinical experience. The sex rate varies from person to person. The overall effect is not very satisfactory, and the efficiency of the type needs to be improved.
