Artery intracavity image reconstruction method, device and equipment and storage medium

Abstract

The invention discloses an image reconstruction method in an artery cavity, which comprises the following steps of: after an imaging probe of a catheter is arranged at a specified position in the artery cavity, driving the imaging probe to move along the axial direction according to a set speed to obtain an original image in the artery cavity; acquiring a motion image of the imaging probe in the motion process in the artery cavity; analyzing the motion image, and determining relative speed data of the artery and the imaging probe; and according to the relative speed data, adjusting the distance of each frame of the original image to obtain a reconstructed image in the artery cavity. By applying the technical scheme provided by the invention, the accuracy of the reconstructed image in the artery cavity is higher, and the artery lesion length measured by the reconstructed image is more accurate, so that reliable numerical evidence can be provided for clinicians to diagnose and determine related treatment schemes. The invention further discloses an artery intracavity image reconstruction device and equipment and a storage medium, which have corresponding technical effects.

Description

technical field [0001] The present application relates to the technical field of computer applications, and in particular, to a method, device, device and storage medium for reconstructing intraluminal images of arteries. Background technique [0002] With the advancement of medical technology, the ability to treat cardiovascular diseases such as coronary heart disease is getting higher and higher, and there are more and more treatment methods. For example, coronary angiography can be used to assess coronary structure and guide percutaneous coronary intervention (PCI). However, the two-dimensional lumen images obtained by coronary angiography cannot reflect the condition of the vessel wall, and cannot evaluate vessel size, plaque characteristics, and stent implantation effects. Intraluminal imaging techniques such as IVUS (intravenous ultrasound, intravascular ultrasound) and OCT (Optical Coherence Tomography, optical coherence tomography) can obtain intracoronary images, w...

AI Technical Summary

Problems solved by technology

However, in reality, due to the heartbeat, the relative movement speed between the coronary artery and the imaging probe of the catheter is not uniform. This equal distance will make the length of the coronary artery lesion measured by the reconstructed image inaccurate, which will affect the clinician's diagnosis. And the determination of related treatment plans, such as inaccurate selection of the length of the implanted stent, and inability to accurately guide coronary interventional treatment, etc.
