Problems solved by technology

[0004] However, the blood in the blood vessel has strong scattering and absorption phenomena on the light signal, resulting in the depth of single-directional OCT imaging often not being able to cover the entire blood vessel

Abstract

The invention discloses an optical coherence tomography system with a reference arm capable of synchronously scanning three-view imaging. The system comprises an OCT core component, a sample arm and the reference arm, optical fibers of the sample end of the OCT core component are connected with a first optical fiber collimator in the sample arm, and optical fibers of the reference end of the OCT core component are connected with a second optical fiber collimator in the reference arm; a first beam scanning galvanometer, a first focusing lens, a first focal length offset wave plate and a sample are arranged in the sample arm in sequence from top to bottom. According to the optical coherence tomography system with the reference arm capable of synchronously scanning three-view imaging, the number of imaging views of the optical coherence tomography system aiming at a tubular structure is effectively increased, and imaging is conducted on the sample in upper, left and right directions, so that the imaging depth of the system is improved through an image mosaic mode, and a good technical solving scheme is provided for comprehensive clear imaging of tubular structures like blood vessels.

Description

technical field [0001] The invention relates to the technical field of medical imaging equipment, in particular to an optical coherence tomography system for synchronously scanning three-view imaging with a reference arm. Background technique [0002] Optical coherence tomography (OCT) is a high-resolution, high-speed, non-invasive optical imaging technology invented by researchers at MIT in the 1990s, which can provide three-dimensional structural imaging for biological tissues. Since its invention, it has been widely used in biomedical research and clinical aspects, such as histomorphological research and real-time navigation of ophthalmic clinical operations. [0003] As a unique application of the optical coherence tomography system, intraoperative blood flow velocity measurement in vascular suture surgery, three-dimensional structure evaluation of thrombus and surgical navigation in intravascular plaque removal surgery are used in the diagnosis, monitoring and treatment...
