Carotid plaque detection method and device based on medical ultrasonic image

Abstract

The invention provides a carotid plaque detection method and device based on a medical ultrasonic image, and the method comprises the steps: building a corresponding relation between a feature parameter in a carotid medical ultrasonic image of a patient and a new vessel perfusion mode in a carotid plaque through the self-learning capability of an artificial neural network; acquiring current feature parameter of the medical ultrasonic image corresponding to the current carotid artery of the patient; determining a new vessel perfusion mode in the current carotid plaque corresponding to the current feature parameter according to the corresponding relationship, specifically, determining a new vessel perfusion mode in the current carotid plaque corresponding to the feature parameter, comprisingdetermining the new vessel perfusion mode in the current carotid plaque corresponding to the feature parameter identical to the current feature parameter in the corresponding relation as the new vessel perfusion mode in the current carotid plaque. The ability of extracting effective features of the neural network is improved, the personnel cost required by detection is reduced, and the accuracy is high.

Description

technical field [0001] The present application relates to the field of medical detection, in particular to a carotid plaque detection method and device based on medical ultrasound images. Background technique [0002] Transient ischemic attack (TIA) is a transient and reversible neurological deficit syndrome, and it is also an important risk factor for cerebral infarction. Studies have shown that the incidence of cerebral infarction after TIA is as high as 8.0% to 10.5%. The carotid artery is the main blood vessel for the brain, and its atherosclerotic plaque is one of the main causes of TIA and cerebral infarction. The latest existing research shows that the perfusion pattern of carotid plaque neovascularization is also one of the independent risk factors for recurrence or ischemic stroke in patients with TIA. [0003] However, in the existing clinical testing, at least two highly qualified ultrasonographic physicians are required to judge the enhancement and grading of t...

Problems solved by technology

[0003] However, in the existing clinical testing, at least two highly qualified ultrasonographic physicians are required to judge the enhancement and grading of the plaques on the obtained contrast-enhanced ultrasound images in order to accurately obtain the neovascular perfusion pattern of the carotid plaques. The diagnostic results required are huge and time-consuming; and due to the human judgment process, it is easy to introduce personal subjective judgment factors, resulting in a decrease in the accuracy of the judgment results
