Abstract

The invention discloses a method for identifying a heart status time phase. The method for identifying the time phase comprises the steps of inputting a three-dimensional heart image of any one phase to obtain the positions of the cardiac apex and the bicuspid valve of the left ventricular of the heart, obtaining a three-dimensional region according to the position information of the cardiac apex and the bicuspid valve, and determining the diastasis and the end-systole of the heartbeat cycle of the heart. The method for identifying the heart status time phase is capable of identifying the heart status time phase quickly, stably and accurately according to the gray-level distribution characteristic of the heart image, and the identification process of the method 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 ...
