High-frame-rate ultrasonic image blood vessel wall motion detail tracking method, system and device and readable storage medium

Abstract

The invention discloses a high-frame-rate ultrasonic image blood vessel wall motion detail tracking method, system and device and a readable storage medium. High-frame-rate ultrasonic imaging is carried out on a blood vessel wall to form a cluster of images, filtering based on singular value decomposition is carried out on the cluster of images, a multi-dimensional matrix for describing information of each frame is recombined, and the multi-dimensional matrix is recovered into the cluster of images; initializing the image, selecting a point on the blood vessel wall of the first frame of image as a central point of a tracking block, defining the size of the tracking block, and selecting the maximum cross-correlation value as a tracking result through cross-correlation calculation to obtain a matched central point and a corresponding image block; analyzing the horizontal and vertical coordinates of the image center point of the tracking result to analyze the heart rate or the vascular elasticity or dynamically playing the tracking result, and observing the image information. And through high-frame-rate imaging, motion detail information of tracking records is increased. And the accuracy of motion tracking is effectively improved by combining the difference between the tissue and blood flow components in the ultrasonic image and the random noise.

Description

technical field [0001] The invention belongs to the technical field of blood vessel wall motion tracking in ultrasonic angiography, in particular to a method, system, device and readable storage medium for tracking the details of blood vessel wall motion in high frame rate ultrasound images. Background technique [0002] With the change of people's lifestyle and eating habits, more and more people will develop vascular-related diseases, such as thrombosis, vascular plaque, atherosclerosis and other diseases. If the corresponding vascular disease occurs in the arteries, it will cause more serious consequences. The same clinical manifestation of these diseases is that the elasticity of the blood vessels changes, that is, the arterial blood vessels become weak with the pulsation of the heart ejecting blood, and the displacement of the blood vessel wall will be very small in one pulsation. [0003] In the existing clinical imaging technology, B-mode ultrasound image, as a tradi...

Problems solved by technology

In practical applications, logic algorithms are gradually replaced by non-logic algorithms. The reason is that there are speckles and nonlinear signals in ultrasound images, which are noise signals for the similarity calculation of ultrasound images, which will seriously affect the quantitative analysis of similarity.

Furthermore, another problem facing vessel wall motion tracking at this stage is that the frame rate of ultrasound images collected by line scan is only about 40Hz, which is not enough to reflect the movement details of the vessel wall
