Problems solved by technology

[0004] However, the study of plaque distribution in the prior art is mainly based on the blood vessel where the plaque is located (eg CN103886599A), the factors considered are not comprehensive enough, and the treatment method evaluated with this reference may not be optimal

Embodiment 1

[0024] This embodiment provides a method for analyzing plaque load in bifurcation lesions, comprising the following steps:

[0025] Step 1, the intravascular ultrasound image (such as figure 1 shown) into the computer to determine the geometric center of the main branch vessel;

[0026] Make the first closed curve along the medial layer of the main branch vessel, calculate and draw the geometric center point 1 of the area contained in the first closed curve (such as figure 2 shown);

[0027] Step 2, determine the geometric center of the branch vessel;

[0028] Make a second closed curve along the media layer of the branch blood vessel, calculate and draw the geometric center point 2 of the area contained in the second closed curve (such as image 3 shown);

[0029] Step 3, connect geometric center point 1 and geometric center point 2;

[0030] Step 4, establish an orthogonal coordinate system;

[0031] Take the geometric center point 1 as the origin, take the line conne...

Abstract

The invention provides an analysis method of plaque load in bifurcation lesion, which comprises: based on IVUS image, plaque is divided into regions, and the plaque load in each region is calculated.The present invention provides the analysis method of plaque load in bifurcation lesion; unlike the convention method that the whole plague load is generally calculated with the vessel where the plague is located, the method establishes an orthogonal coordinate system according to the relative position of the main branch blood vessel and the branch blood vessel, and divides the plaque load into regions; through the quantitative analysis method of region division, doctors can find the correlation of prognosis cause by the treatment method of different plaque loads and bifurcation lesion and find the optimal treatment method through evaluation, so the method has an important application prospect in clinical research.

Description

technical field [0001] The invention relates to the field of medical image processing and analysis, in particular to an analysis method for plaque load in bifurcation lesions. Background technique [0002] At present, cardiovascular and cerebrovascular diseases have gradually become an important factor that endangers people's life and health. Coronary atherosclerotic lesions are the main cause of myocardial infarction and cerebral infarction. Coronary bifurcation lesions refer to lesions with severe stenosis in the main branch and branch of the coronary artery separately or simultaneously, accounting for all percutaneous coronary intervention. 15%-20% of coronary artery disease is the difficulty of coronary intervention. The classification of bifurcation lesions is mainly based on the anatomical distribution of lesions at the bifurcation site, and the commonly used ones include Duke classification, Lefevre classification, and Medina classification. However, these classific...
