Problems solved by technology

[0004] Although clinical studies have initially suggested that the digital surgical planning system can help improve the accuracy and safety of liver resection, but because the digital surgical planning system has been used in liver resection for a short time, its value and status in liver resection Still needs further testing, especially systematic research according to the principles of evidence-based medicine

Abstract

The invention discloses a three-dimensional structural description method of hepatic vascular system, which belongs to the field of medical liver division. The method comprises the following steps of: firstly, dividing a hepatic image and a hepatic vascular image, structurally analyzing the hepatic vascular three-dimensional image, skeletonizing the liver and the blood vessel, and marking the skeletonized voxel points; next, storing the marked voxel points to data structure of multi-branch tree; then, distinguishing main and branch blood vessels according to master slave relation of the voxelpoints in the multi-branch tree; finally, dividing the liver body into multiple liver segments according to relation between the blood vessels in the hepatic vascular system. By the three-dimensionalstructural description method of hepatic vascular system, accurate division of liver is realized so that guidance is provided for accurate removal of liver.

Description

technical field [0001] The invention relates to the liver vascular system, in particular to a three-dimensional structural description method of the liver vascular system. Background technique [0002] In recent years, with the development of science and technology, the use of computer graphics and data visualization technology, computer image processing and analysis methods, and 3D reconstruction can help doctors construct 2D image data into a three-dimensional 3D visualization model, clearly showing the pipeline system in the model Complicated running, distribution, and spatial structure position relationship, while realizing quantitative analysis of image data, providing information such as the diameter, length of the pipeline, and the area of ​​​​the parenchymal organs it governs. On the basis of the 3D visualization model, virtual cutting is carried out, and a computer-aided surgical planning platform is established, so that the preoperative evaluation of surgical feasi...
