Abstract

The invention provides a carotid plaque segmentation method and device based on artificial intelligence and a storage medium, and the method comprises the steps: obtaining an original mode image slice, and recognizing a bifurcated slice based on the original mode image slice; marking initial boundary points of the bifurcated slices, and interpolating the marked initial boundary points to create a continuous initial boundary; and refining the initial boundary through a distance regularization level set to obtain an intima boundary and an outer wall boundary of a carotid plaque blood vessel cavity, and obtaining the carotid plaque. According to the technical scheme provided by the invention, the carotid plaque is automatically segmented by using brand new 3DUS imaging based on a plaque segmentation integrated framework of 3DUS and deep learning, the accuracy of carotid plaque segmentation is improved, the plaque burden can be more comprehensively measured, and the recognition of the carotid plaque is more accurate.

Description

technical field [0001] The present invention relates to artificial intelligence and arterial detection technology, in particular to an artificial intelligence-based carotid plaque segmentation method, device and storage medium. Background technique [0002] Atherosclerosis is the main pathophysiological process of atherosclerotic cardiovascular disease (ASCVD), mainly distributed in coronary arteries, carotid arteries, cerebrovascular and peripheral arteries. Internal carotid artery plaques most commonly occur at the carotid bifurcation, which is not only a marker of carotid atherosclerosis, but also a risk predictor of future ischemic events. Carotid atherosclerosis is an important cause of stroke. Ultrasound imaging has been widely used in the diagnosis of atherosclerosis. [0003] The shape of carotid plaque is thought to play a very important role in its subsequent development and rupture. Prevention of (recurrent) cerebral ischemia is the goal of medical or surgical ...
