Abstract

The invention provides a method for segmenting an inner myocardial membrane and/or an outer myocardial membrane of a left ventricle of a heart, and the method comprises the steps: obtaining a 3D image containing the heart through a processor; based on the 3D image, segmenting the left ventricular myocardium to obtain a 3D segmentation result of the left ventricular myocardium; based on the 3D segmentation result of the left ventricular myocardium, extracting an inner myocardial membrane and/or an outer myocardial membrane of the left ventricle; and displaying the extracted inner and/or outer myocardial membranes of the left ventricle. The method can improve the segmentation efficiency, reduce the segmentation error and improve the segmentation accuracy.

Description

technical field [0001] The present disclosure relates to the field of image processing, and more particularly, to a method and device for segmenting endocardium and / or epimyocardium of the left ventricle of the heart. Background technique [0002] Segmentation of left ventricular myocardium is an important step in cardiac function analysis. Functional evaluations such as left ventricular wall thickness and ejection fraction, and diagnosis and treatment of hypertrophic cardiomyopathy are all based on accurate segmentation of left ventricular myocardium. In the image of the left ventricle of the heart, since the gray values ​​of the left ventricular endocardium and papillary muscle, trabecula and other tissues are very close, and the gray value difference between the left ventricular epicocardium and the external adjacent tissues is small, the segmentation task has a large challenging. [0003] Based on traditional image processing methods, a 3D image is generally given and i...
