Abstract

The invention discloses an indocyanine green-loaded carbon nanotube-mediated optical coherence tomography method and system. The system comprises a sample injected and infiltrated with a carbon nanotube solution loaded with indocyanine green, a light source system, a reference arm light path system, a sample arm light path system, a spectrograph system and a linear array CCD camera light signal acquisition system. Through the sample injected and infiltrated with a carbon nanotube solution loaded with indocyanine green, the light source system, the reference arm light path system, the sample arm light path system, the spectrograph system and the linear array CCD camera light signal acquisition system, tomography is achieved, signals of the area injected with the carbon nanotube material solution loaded with indocyanine green is successfully restrained, the contrast ratio of acquired images is effectively improved, operation is easy, safe and easy to achieve, and the OCT imaging contrastratio is effectively improved. The method can be used for optical coherence tomography.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to a method and system for optical coherence tomography mediated by carbon nanotubes loaded with indocyanine green. Background technique [0002] Optical coherence tomography (OCT) is an optical imaging method developed in the past 20 years. It was originally used to study the monitoring imaging of optical fiber sections. OCT obtains tomographic capabilities in the depth direction based on the principle of low-coherence interference, and reconstructs two-dimensional or three-dimensional images of the internal structure of biological tissues or materials through scanning. The signal contrast comes from the space of optical reflection (scattering) characteristics of biological tissues or materials. Variety. The light absorption of biological tissues in the near-infrared region is very weak. Therefore, in order to display deeper biological tissue structures, OCT systems genera...
