Quantitative analysis method and device for three-dimensional structural characteristics of liver vein blood vessel, computer equipment and storage medium

Abstract

The invention provides a liver vein three-dimensional structural feature quantitative analysis method, and the method comprises the following steps: acquiring a to-be-analyzed liver three-dimensional image, and acquiring a segmentation region of a vein; calculating a center line; segmenting the blood vessel, and dividing the vein blood vessel into left, middle and right veins of the liver and left and right branches of the portal vein of the liver; according to the center line of each section and a vein model reconstructed by using a three-dimensional surface reconstruction algorithm, carrying out quantitative analysis on the three-dimensional structure characteristics of the vein, wherein the parameter indexes comprise one or more of a blood vessel form, a branch and a grid characterization index. The invention further provides a related device, computer equipment and a storage medium. Due to the fact that manual intervention is not needed, full-automatic analysis can be achieved, and the requirement for analyzing blood vessel parameters in batches can be met, the three-dimensional structure characteristic quantitative indexes of liver vein blood vessels can be rapidly and accurately analyzed in batches, and more comprehensive and detailed blood vessel three-dimensional structure characteristic quantitative analysis can be provided; and a more comprehensive reference can be provided for a doctor to evaluate blood vessels.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to the technical field of quantitative analysis of three-dimensional structural features of blood vessels, and specifically refers to a quantitative analysis method, device, computer equipment and storage medium for three-dimensional structural features of liver veins and blood vessels. Background technique [0002] Many diseases will cause changes in the shape of blood vessels to a certain extent, so the early prediction and clinical diagnosis of some diseases can be carried out through the quantitative analysis of blood vessels. Since 2D vascular quantitative analysis is often affected by structural overlap, 3D vascular quantitative analysis results are more accurate. [0003] At present, there are already some software or patents for vascular parameter assessment on the market, and their content still has certain defects or incompleteness. For example, the evalu...
