Combined endoscope imaging system based on OCT (Optical Coherence Tomography) and imaging method

Abstract

The invention discloses a combined endoscope imaging system based on an OCT (Optical Coherence Tomography) and an imaging method. The combined endoscope imaging system comprises an endoscope imaging device which is controlled by a computation control unit and is provided with an OCT imaging system and a photoelectric imaging or image guide optical fiber imaging system; the endoscope imaging device comprises a reference arm and an endoscope with a sample arm; the endoscope is internally provided with a plurality of channels; and each channel is internally provided with an OCT imaging probe, a photoelectric imaging probe or an image guide optical fiber bundle and a light guide fiber bundle. OCT imaging and photoelectric imaging or image guide optical fiber bundle imaging are combined to realize real video images on the surface and the periphery of a tissue of an observed position in real time and obtain a two-dimensional tomography image under a certain depth of the skin of the tissue at the position. A visible light source 2 also can be added to be coupled into the OCT imaging system so that an OCT imaging probe scanning light bundle is accurately positioned to a target region and the accurate positioning and scanning of a pathological change region of the tissue of a sample can be realized.

Description

technical field [0001] The invention relates to an endoscope device, in particular to an OCT-based compound endoscope imaging system and an imaging method, belonging to the technical field of endoscope imaging. Background technique [0002] Most of the core technologies of traditional endoscopes use image-guiding optical fiber bundles or photoelectric imaging for imaging. This type of endoscope can only observe from the surface of the tissue, but the symptoms of early cancer often occur at a depth of 1-3 mm below the epidermis , so the above-mentioned endoscope then appears powerless. In addition, there are also endoscopes that perform medical imaging through the principle of ultrasound. This type of endoscope can obtain deeper tissue information below the surface of biological tissues, but the resolution is only on the order of millimeters, and cannot effectively detect and diagnose fine tissues. [0003] In order to solve the above problems, the endoscope device of the pr...
