Abstract

The invention discloses a cardiac motion representation method and device and a computer readable storage medium. Extracting the MR image of the first phase and the second phase to be processed and constructed so as to obtain a first phase cardiogram structure A and a second phase cardiogram structure Bi; a vertex set with the corresponding relation is obtained by solving the graph matching convexobjective function by using the two cardiogram structures; a deformation function is constructed based on the vertex set with the corresponding relation, and deformation of Bi is performed by using the deformation function so as to obtain a new second phase cardiogram structure Bi+1; and calculating the change value of Bi and Bi+1 and judging whether the change value is greater than the preset threshold value, if so, i=i+1 and circulating the steps, or using the deformation function to represent the cardiac motion. According to the method, the deformation function is constructed by the cycling mode and then the original structure is deformed by using the constructed deformation function, and the accuracy of the deformation function is further checked according to the deformation change value so that the method can more accurately represent the cardiac motion.

Description

technical field [0001] The present invention relates to the field of computer technology, and more specifically, to a heart motion characterization method, device and computer-readable storage medium. Background technique [0002] The use of cardiac image analysis to track the anatomical structure of the heart and the movement changes of heart lesion tissue, that is, to analyze the heart movement, is an important means for the diagnosis of heart disease and the formulation of treatment plans. The existing registration method based on B-spline free deformation and optical flow method Neither the method nor the shape-based structure can accurately characterize the motion of the heart, so how to use the structural characteristics of the myocardium to characterize the motion of the heart more accurately is an urgent problem to be solved. Contents of the invention [0003] The main purpose of the present invention is to provide a heart motion characterization method, aiming at ...
