Method and system for echocardiogram synthesis with myocardium motion modeling using a combination of diffusion model and neural ordinary differential equations

Abstract

Disclosed are a method and a system for synthesizing echocardiogram video segments with myocardium motion modeling using a combination of diffusion model and neural ordinary differential equations. The method includes the steps of: synthesizing the video echocardiography video that conditions the segmentation map of the first frame of the cardiac cycle (end-diastole) using a video diffusion model; estimating the motion, or a diffeomorphic registration between a given frame from generated video and the first frame of the cardiac cycle using a neural ordinary differential equation (ODE) model; and obtaining an annotated echocardiogram video by propagating the segmentation map of the first frame of the cardiac cycle through the generated video using the estimated motion.
