Problems solved by technology

The disadvantage of this system is that the infrared rays cannot be blocked by obstacles, which brings deficiencies to the operation of the surgery, and this technology is not suitable for interventional therapy
[0009] The current OCT examination does not combine the data of the withdrawn main branch vessels and branch vessels, and cannot provide the surgeon with a three-dimensional visual three-dimensional map of the vessels. Effectiveness in Coronary Bifurcation Lesions

Abstract

Provided in the invention is an OCT three-dimensional visualization system based on coronary artery bifurcation lesions. The system comprises an OCT image acquisition module, a real-time position tracking module, an image space position correction module, a blood vessel bifurcation registration fusion module and a three-dimensional rendering module. Besides, a working method comprises the steps ofOCT image acquisition, correction, data splicing and fusion, blood vessel inner wall information extraction, rendering and three-dimensional reconstruction. The system is simple in structure and easyto implement; an external electromagnetic wave generating device is not relied on, the cost is low and the anti-interference capability is strong; the visualization effect is good; and the accuracy is high.

Description

[0001] (1) Technical field: [0002] The invention relates to the field of medical auxiliary medical equipment, in particular to an OCT three-dimensional visualization system and working method based on coronary bifurcation lesions. [0003] (two) background technology: [0004] Optical interference tomography (Optical Coherence Tomography, OCT) is another new intravascular imaging technology following X-ray, CT (Computed Tomography, Computed Tomography), MRI (Magnetic Resonance Imaging, Magnetic Resonance Imaging) and ultrasound diagnostic techniques. Imaging method. It integrates optical technology, ultra-sensitive detection technology and computer image processing technology, and can quickly obtain high-resolution microstructure images of blood vessel cross-sections. [0005] The advent of OCT has greatly made up for the lack of coronary angiography, which can identify normal blood vessels, lipid plaques, fibrous plaques, calcified plaques, and vulnerable plaques. The gene...
