Nail fold microcirculation blood vessel three-dimensional scanning analysis system and method

Abstract

The invention provides a nail fold microcirculation blood vessel three-dimensional scanning analysis system. The nail fold microcirculation blood vessel three-dimensional scanning analysis system comprises a low-coherence light source, an optical fiber coupler, a reference arm, a sample arm, a spectrograph, a CCD camera, a three-dimensional displacement device and an upper computer; the low-coherence light source is used for emitting a light beam; the optical fiber coupler is used for carrying out light splitting processing on the light beam and carrying out interference processing on a reference light signal reflected by the reference arm and a nail fold light signal reflected by the sample arm; the spectrograph is used for receiving the reference light signal and the nail fold light signal and generating an interference spectrum according to the reference light signal and the nail fold light signal after interference processing; the CCD camera is used for collecting the interference spectrum and converting the interference spectrum into interference digital signals; the upper computer is used for receiving the interference digital signals and generating a nail fold microcirculation blood vessel three-dimensional view according to the interference digital signals; and the sample arm is fixedly installed on the three-dimensional displacement device. According to the system, rapid scanning analysis of the three-dimensional image of the nail fold microcirculation blood vessel can be realized.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a three-dimensional scanning analysis system and method for nailfold microcirculation blood vessels. Background technique [0002] Microcirculation generally refers to the blood circulation located at the end of the blood circulatory system (ie, between arterioles and venules), which is the site of material exchange between blood and tissues. In human microcirculation, common observation and detection sites include nailfold microcirculation, sublingual microcirculation, eyeball microcirculation, gingival microcirculation, etc. The nailfold microcirculation blood vessels are located about 200 microns below the skin of the nail tip, roughly parallel to the skin surface. Since the fingers are easy to fix, it is possible to prevent excessive shaking from having a great influence on the observation. The research on the morphology of nailfold microvessels can assist in the d...

Problems solved by technology

[0004] Based on this, in order to solve the problem that the traditional nailfold microcirculation detector needs to manually adjust the position of the sample arm to focus the objective lens when observing the nailfold microcirculation, the present invention provides a nailfold The system and method for three-dimensional scanning and analysis of microcirculation blood vessels, the specific technical solutions are as follows:

Through the optical coherence tomography technology, and using the three-dimensional displacement device to automatically realize the automatic focusing of the objective lens in the sample arm, it can solve the need for manual adjustment when the traditional nailfold microcirculation detector observes the nailfold microcirculation The position of the sample arm is to focus on the objective lens, but there is a problem of low work efficiency, which can realize fast scanning analysis of three-dimensional images of nailfold microcirculation vessels
