Problems solved by technology

Due to the thin-layer structure of the left ventricular myocardium, the direct prediction of the myocardium is very demanding on the accuracy of the segmentation. Without the prior knowledge of other positions as an auxiliary, the problem of segmentation deviation is easy to occur. Therefore, this segmentation idea is in a certain less robust in the sense

Abstract

The present disclosure provides a method for segmenting the endocardium and / or epimyocardium of the left ventricle of the heart, including, via a processor: acquiring a 3D image containing the heart; 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 the endocardium and / or epimyocardium of the left ventricle; and displaying the extracted endocardium and / or epicocardium of the left ventricle . This method can improve segmentation efficiency, reduce segmentation error, and improve segmentation accuracy.

Description

technical field [0001] The present disclosure relates to the field of image processing, and more particularly, to a method and apparatus for segmenting the endomyocardium and / or epimyocardium of the left ventricle of the heart. Background technique [0002] The segmentation of the left ventricular endocardium and endocardium of the heart is an important step in the analysis of cardiac function. The functional evaluation of the left ventricular myocardial wall thickness and ejection fraction, and the diagnosis and treatment of hypertrophic cardiomyopathy are all based on the accurate segmentation of the left ventricular myocardium and endocardium. In the image of the left ventricle of the heart, because the gray values ​​of the left ventricle endocardium, papillary muscles, trabeculae and other tissues are very close, and the gray value difference between the left ventricle epimyocardium and the external adjacent tissues is small, the segmentation task has a great effect. cha...
