Embodiment Construction

[0078] In the following, the present invention will be further described in detail in conjunction with specific implementation examples and descriptions of the drawings, and the solution verification of the present invention will be given.

[0079] A method for extraction and thickness measurement of aortic carotid artery CCA vessels based on ultrasound images of the neck, including the following five steps and protocol verification, such as figure 1 Shown; Specifically, the flow chart of image processing for each two-dimensional sequence, such as figure 2 Shown; the overall flow chart, as shown in 3.

[0080] Step (1) Read the neck ultrasound three-dimensional volume data 3D_Data, mark the main carotid bifurcation point "BF" and the central axis, such as Figure 4 shown.

[0081] (1.1) Locate the bifurcation point "BF"

[0082] In the three-dimensional ultrasound volume data 3D_Data, identify the main carotid artery CCA, internal carotid artery ICA and external carotid ar...

Abstract

The invention discloses a main carotid artery blood vessel extraction and thickness measuring method based on neck ultrasound images. The method comprises the following specific steps of: reading neck ultrasound three-dimensional body data, and marking a main carotid artery axis based on a main carotid artery branching node; sequentially projecting and segmenting the neck ultrasound three-dimensional data in the three-view drawing direction to obtain two-dimensional cross section, coronal plane and vertical plane sequence images; and preprocessing, dividing and reconstructing the two-dimensional cross section, coronal plane and vertical plane sequence images or counting the thickness of intima-media membrane to obtain the final relevant information of internal and external profiles of the neck ultrasound main carotid artery blood vessel wall and the thickness of the blood vessel wall. By the method, the defects that the calculating complexity in the blood vessel dividing method is high, the thickness of the blood vessel wall cannot be accurately measured and an error is likely to be caused by subjective factors during computer-aided diagnosis are overcome, and the internal and external profiles of the neck ultrasound main carotid artery blood vessel wall and the thickness of the blood vessel wall can be completely, rapidly and accurately obtained. In comparison with the manual dividing method, the method is rapid in operation, and can be used for auxiliary diagnosis and prevention and treatment of neck atherosclerosis and cardiovascular disease.

Description

technical field [0001] The invention belongs to the cross field of biomedical engineering and image processing, and in particular relates to a method for extracting and measuring the thickness of a main carotid artery based on ultrasound images of the neck. Background technique [0002] According to the latest statistics from the World Health Organization, cardiovascular diseases (Cardiovascular Diseases, CVDs) are one of the three leading causes of death in the world. Arterial wall thickening, plaque formation, and narrowing of blood vessels is one of the typical symptoms of atherosclerosis. Carotid atherosclerosis is a cardiovascular and cerebrovascular disease that can cause heart disease and stroke, and seriously endangers human health. Therefore, its early prevention, diagnosis, treatment and monitoring are of great significance. [0003] On January 20, 2010, the American Heart Association (American Heart Association, AHA) Strategic Planning Working Committee released...
