Problems solved by technology

[0005] The purpose of the present invention is to provide a near-infrared bispectral fluorescence imaging method and system based on spectral response characteristics on the same screen, aiming to solve the problem that the existing dual-camera split-mode imaging system needs to switch modes frequently for separate observation, which is not conducive to surgical operations. And the optical path of the three-camera spectroscopic imaging system is relatively complex, the structure is bloated, and it is not conducive to integration

Abstract

The invention discloses a same-screen near-infrared bispectral fluorescence imaging method and system based on spectral response characteristics, using the different response characteristics of dye fluorescence peak bands in the near-infrared range of a color camera with an RGB Bayer filter, and matching specific channels Electronic amplification enhances the difference between the two types of fluorescent RGB components collected to form image signals of different colors. The algorithm marks the two fluorescent colors on the white light image respectively according to the RGB components to realize dual-spectrum near-infrared fluorescent imaging on the same screen; the invention is based on spectral response The optical path of the characteristic same-screen near-infrared bispectral fluorescence imaging system is relatively simple, and the structure is compact, which is conducive to integration.

Description

technical field [0001] The invention relates to the field of optical imaging, in particular to a method and system for near-infrared bispectral fluorescence imaging on the same screen based on spectral response characteristics. Background technique [0002] Near-infrared fluorescence contrast technology is currently widely used in intraoperative navigation. On the basis of obtaining white light and fluorescent signals separately, the near-infrared fluorescent signal is marked on the white light image through an algorithm, and provides specific dye-labeled lymphatic, vascular and bile ducts for the operator. and location information of biological tissues such as tumors. Clinically, multiple dyes can be used to mark different biological tissues in the same operation, such as marking blood vessels and bile ducts respectively. [0003] At present, on the basis of white light images, the systems that can perform fluorescence imaging of two dyes and superimpose labeling mainly us...
