Carotid plaque property judgment method, storage medium and ultrasonic device

Abstract

The invention relates to the technical field of ultrasonic medical image processing, and particularly discloses a carotid plaque property judgment method, which comprises the following steps of obtaining an ultrasonic radiography video comprising a carotid plaque; identifying the ultrasound contrast video through a first neural network to obtain an angiography video, the angiography video comprising an image stream of an area where plaque blood vessels are located in the ultrasound contrast video; extracting the image features in the angiography video through a feature extraction model; and identifying the image features through a second neural network to obtain the property category of the plaque. The invention further discloses a storage medium and an ultrasonic device. According to thecarotid plaque property judgment method and device provided by the invention, the nature category of the plaque can be effectively identified, and the qualitative analysis of the carotid plaque is realized, so that an important basis is provided for the medical personnel to analyze and diagnose the carotid plaque.

Description

technical field [0001] The present invention relates to the technical field of ultrasonic image processing, in particular to a method for judging the nature of carotid plaque, a storage medium for storing program instructions for executing the method for judging the nature of carotid plaque, and an ultrasound device including the storage medium. Background technique [0002] The harm of carotid plaque is related to the nature, location and shape of the plaque. Carotid plaques include vulnerable plaques and stable plaques. Among them, the main risk of carotid vulnerable plaque is ischemic stroke. Vulnerable plaques are also called soft plaques and unstable plaques. The plaques are irregular in shape and easy to fall off. After falling off, they can block the cerebral blood vessels with the blood flow and cause ischemic stroke, resulting in hemiplegia, aphasia, eye Crooked mouth and other symptoms. In patients with stable plaques, the plaques are calcified, more solid, less...

AI Technical Summary

Problems solved by technology

Traditional two-dimensional ultrasound can only see the position, size, shape, echo and other characteristics of the plaque, but the internal characteristics of the plaque cannot be detected. CEUS can not only display the size, shape, edge and residual official cavity of the plaque, but also display The new blood vessels in the plaque, the new blood vessels in the plaque have a certain reference effect on the vulnerability / stability of the plaque. For the plaque with new blood vessels, it is easy to rupture and bleed, causing the plaque to rupture and fall off, while the carotid artery plaque One of the most important reasons for stroke
