specific Embodiment approach

[0034] The specific embodiment of the present invention is summarized as 4 steps:

[0035] 1). Display blood vessel (depth and direction) indicator cursor on 2D black and white image;

[0036] 2).Under the control of the blood vessel (depth and direction) indicator cursor, the blood vessel diameter information is extracted from the original digital radio frequency echo data of the blood vessel, and the blood vessel diameter data and the change data of the blood vessel diameter are obtained;

[0037] 3). Determine the absolute diameter of the blood vessel according to the blood vessel (depth and direction) indicating cursor and blood vessel diameter information;

[0038] 4). According to the above-mentioned blood vessel diameter data and change data of blood vessel diameter and the absolute diameter of blood vessels, combined with the ECG information and blood flow spectrogram obtained by the ultrasound imaging system, the blood flow, blood vessel fluctuation curve and blood fl...

Abstract

The invention relates to a method for extracting two-dimensional dynamic blood vessel information based on ultrasonic echo in real time, which comprises the following steps: forming and displaying a blood vessel indication cursor on an ultrasonic two-dimensional image; conducting extraction on the information about the blood vessel diameter for the original blood vessel digital radio frequency echo data to obtain the blood vessel diameter data and the blood vessel diameter variation data, wherein the representation unit of the diameter information is the number of sampling points; determining the actual diameter and fluctuations of the blood vessel according to the blood vessel indication cursor and the information about the blood vessel diameter; and further calculating blood flow volume, the fluctuation range and characteristic points of the blood vessel as well as blood flow diameter arc graphs according to the blood vessel diameter information of the blood vessel diameter variation information by combining other existing information, namely electrocardiogram information and blood flow frequency spectrogram, thus obtaining real-time two-dimensional dynamic blood vessel information. According to the invention, an analysis tool is provided for dynamic assessment of blood flow / blood vessel and compliance / elastic analysis of the blood vessel, pressure signals in the axial and radial directions of the blood vessel are provided for pulse condition analysis and research, and the extraction method has the characteristics of practical applicability and clinical practice.

Description

technical field [0001] The invention relates to a medical information processing technology, in particular to a method for extracting real-time two-dimensional (radial and axial) dynamic information of blood vessel walls based on ultrasonic echoes. Background technique [0002] The metabolism and physiological state of human organs reflect the health status of the human body. The circulatory system is responsible for transporting various substances needed by various organs, as well as various waste products produced after metabolism. For example, oxygen enters the human body through the blood in the lungs; ribose / low sugar and other protein-structuring substances are carried by the blood in the digestive system and sent to various organs; harmful gases in the metabolites are discharged in the lungs through the blood; other metabolites, It is transformed by the blood in the liver, or filtered by the kidneys to form urine and finally excreted from the body. When the physiolo...
