Abstract

A left ventricular myocardial segmentation method, device and compute readable storage medium are disclosed, wherein, that left ventricular myocardial segmentation method comprises the follow steps of: obtaining a heart image; for the heart image, N times of down-sampling convolution processing and extraction of the first feature information are performed iteratively; if the iterative process of extracting the first feature information is completed for N times, performing N times of up-sampling convolution processing and extracting the second feature information for the output object of the Nth down-sampling convolution processing based on the first feature information extracted for the Nth time; if the iterative process of extracting the second feature N times is completed, the left ventricular myocardium is automatically segmented based on the pre-trained classifier. The technical proposal provided by the present application can effectively improve the efficiency of left ventricularmyocardial segmentation.

Description

technical field [0001] The present application relates to the field of biomedicine, and in particular to a left ventricular myocardium segmentation method, device and computer-readable storage medium. Background technique [0002] Segmentation of left ventricular myocardium is the main step in cardiac function analysis. Cardiac function analysis parameters such as left ventricular myocardial wall thickness and ejection volume are all based on accurate segmentation of left ventricular myocardium. The gray scale of the left ventricular myocardium is similar to that of the background, and the papillary muscle and trabeculae in the left ventricle belong to the same substance as the myocardium, and there are artifacts. Therefore, left ventricular myocardium segmentation is a difficult but important task. [0003] Currently, methods for left ventricular myocardium segmentation mainly use magnetic resonance imaging (Magnetic Resonance Imaging, MRI) technology to obtain heart image...
