Artery intracavity ultrasound imaging method, artery intracavity ultrasound imaging device, equipment and artery intracavity ultrasound imaging system

Abstract

The invention discloses an artery intracavity ultrasonic imaging method. The withdrawing speed of a probe is determined according to relative speed change data between a target artery section and an ultrasonic probe when the ultrasonic probe is static, so that the influence of the movement process of the artery cavity along with the heartbeat on the withdrawing image acquisition process of the probe can be reduced; loss of useful data can be avoided while repeated imaging is avoided; an appropriate number of arterial cavity images are enabled to be acquired; the occurrence of image distortion is avoided; the accuracy of withdrawing image acquisition is improved, so that a reliable length value is provided for an arterial intervention doctor in the arterial intervention treatment process, and the accuracy of the arterial lesion length measured according to artery intracavity ultrasonic imaging is improved; and the diagnosis and treatment effect can be effectively improved. The invention also discloses an artery intracavity ultrasonic imaging device, computer equipment, a computer readable storage medium and an artery intracavity ultrasonic imaging system, which have the beneficial effects.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an arterial intracavity ultrasonic imaging method and device, a computer device, a computer-readable storage medium and an arterial intraluminal ultrasonic imaging system. Background technique [0002] Cardiovascular disease is the number one health killer in the world, and it is also the main cause of death among Chinese residents. Among them, coronary heart disease is one of the diseases with the highest mortality and disability rates, and it is also the disease with the fastest growing mortality rate in my country. [0003] Vascular imaging techniques such as coronary angiography can evaluate vessel size, plaque characteristics, and stent implantation effects, etc. The size of the lumen and lesion characteristics can be evaluated before surgery, and the postoperative intraluminal imaging enables the operator to evaluate the stent at the stent level The effect of im...

Problems solved by technology

Although coronary angiography and other vascular imaging techniques are considered the "gold standard" for evaluating coronary artery disease, there are still certain limitations. For example, angiography cannot make a functional judgment of stenosis, and (angiography) imaging only shows the lumen Therefore, we need a "third eye"—IVUS (intravascular ultrasound) and other intravascular ultrasound imaging techniques to see through arteries (such as coronary arteries) and obtain intra-arterial images. Understanding the situation in the arterial lumen and evaluating its physiological characteristics, so as to choose a reasonable treatment strategy, provide more important information for optimizing stent implantation and reducing stent-related problems in clinical practice

[0004] At present, the retraction of intra-arterial ultrasound imaging includes two modes: slow and fast. Slow retraction means longer imaging time. At the same time, with the contraction and relaxation of the heart, repeated imaging and "sawtooth" phenomenon will appear in ultrasound imaging; Fast retraction means that the retraction distance of the imaging probe per unit time is large, resulting in too large a distance between each frame of imaging, and more blood vessel and lesion information will be lost, which further leads to the problem of inaccurate measurement of the length of arterial lesions, which in turn leads to The selection of the length of the implanted stent is inaccurate, and the arterial interventional treatment cannot be accurately guided
