Abstract

A method and device for identifying the time phase of the heart state. The time phase identification method includes: inputting a three-dimensional image of any phase of the heart to obtain the positions of the apex and mitral valve of the left ventricle of the heart; according to the apex and bicuspid The position information of the cusp valve is used to obtain a three-dimensional area; according to the image information in the three-dimensional area, the end-diastole and end-systole of the cardiac cycle are determined. The technical solution quickly, stably and accurately recognizes the time phase of the heart state based on the gray scale distribution characteristics of the heart image, and the recognition process is simple and completely automatic.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method for identifying time phases of cardiac states. Background technique [0002] In the analysis of cardiac function, the usual method is to select the end-diastole (end-diastole, ED) and end-systole (end-systole, ES) of a heartbeat cycle to calculate various cardiac function indexes, such as ejection fraction, local myocardial changes, myocardial Variations in wall thickness, etc. Therefore, it is necessary to determine the images corresponding to the time phase of ED and ES in the analysis of cardiac function. [0003] At present, the methods for determining the phase of ED and ES mainly include manual observation method, ECG auxiliary judgment method, image post-processing methods such as volume judgment method and phase image gray value correlation method, etc. The manual observation method is to read the images of each phase of the heart, find the position of the left ...
