Abstract

The present application provides a left ventricle segmentation method, device and electronic device, wherein the method includes: acquiring cardiac medical image data; determining the cardiac apex position and the cardiac base position in the medical imaging data according to the cardiac physiological structure characteristics; based on the cardiac apex position and the cardiac base position The location of the heart base was determined by the regional growth algorithm. According to the segmentation results of the left ventricular chamber, the segmentation results of the left myocardium were obtained based on the level set algorithm. The segmentation results of the left ventricle were obtained by combining the segmentation results of the left ventricular chamber and the left myocardium. Since the apex and the heart base are located in the ventricle, the regional growth method based on the apex and the heart base can obtain relatively accurate segmentation results of the left ventricular cavity. Based on the segmentation results of the left ventricular cavity, the level set algorithm is used to perform accurate segmentation of the left myocardium, and the evolution speed is fast.

Description

technical field [0001] The present application relates to the technical field of medical images, in particular to a left ventricle segmentation method, device and electronic equipment. Background technique [0002] Heart disease has become the number one killer of human health in recent years. How to effectively and accurately diagnose cardiovascular disease has become the number one topic for medical workers. From the perspective of heart mechanism, the left ventricle, which is responsible for supplying blood to various organs of the body, is the most important part of the heart. Therefore, abnormalities in its shape and movement are used as an important basis for evaluating cardiac lesions. With the development of medical imaging technology, non-invasive analysis of cardiac function based on the left ventricle has become an important auxiliary means for clinical diagnosis of heart diseases. [0003] At present, there are many imaging methods for cardiac function analysi...
