Myocardial Shape, Motion, and Deformation Analysis Methods in Two-dimensional Echocardiography Sequences

Abstract

The present invention proposes a method for analyzing myocardial shape, movement and deformation in a two-dimensional echocardiogram sequence, which includes the following steps: firstly, a preprocessing unit is used to preprocess the two-dimensional echocardiogram sequence to be analyzed, so as to obtain cardiac cycle myocardial wall The coordinates of each point, and the direction of each point of the myocardial wall at each moment of the cardiac cycle are displayed on the visualization unit; then the myocardial motion shape calculation unit calculates the myocardial shape, displacement, velocity and longitudinal strain according to the coordinates of each point of the myocardial wall in the cardiac cycle, This allows an intuitive understanding of cardiac mechanics, in particular myocardial shape, motion and deformation. The present invention analyzes the images at each moment in the heart cycle, thereby displaying the myocardial shape, movement and deformation during the heart movement, meeting the requirements of real-time processing in clinical practice, and effectively avoiding the accidental existence of some still images in clinical practice It is convenient for clinicians to make correct judgments.

Description

technical field [0001] The invention relates to the fields of medical image processing and intelligent health management, in particular to a method for analyzing myocardial shape, movement and deformation in a two-dimensional echocardiogram sequence. Background technique [0002] Cardiac diseases such as coronary heart disease are currently one of the main causes of human death, and medical imaging technology plays an important role in the diagnosis and treatment of heart diseases. Echocardiography is noninvasive, safe and reliable, and is widely used in clinical diagnosis of heart disease. The study of the motion of the heart by 2D echocardiography, especially the study of the left ventricle, is at the center of attention. Although the motion of the heart can be observed directly from two-dimensional real-time ultrasound images, there is still potential for major improvements in its diagnostic quality. Since real-time observation is basically a qualitative evaluation, it ...

AI Technical Summary

Problems solved by technology

The shortcomings of this method are: (1) PET heart image is a three-dimensional image, and the amount of data that needs to be processed at each moment in the heart cycle is very huge, which is difficult to meet the requirements of clinical practice for real-time processing

(2) Only the heart contour is extracted by using PET heart images, but the myocardial motion and deformation information is not analyzed, which has limited effect on improving clinical diagnosis
