By adopting the system and the method, the problem that at present, most endoscope fluorescent products can only see fluorescent images or visible light images but not multispectral images is solved, technical monopoly of foreign companies in China is broken through, the imaging research threshold of the multispectral endoscope is lowered, the selection space of optical molecular imaging probes is expanded, and the optical molecular imaging research and application ranges are extended.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an endoscope-based multispectral video navigation system and method. Background technique [0002] In recent years, due to the continuous development of molecular imaging technology, after radionuclide imaging, positron emission tomography, single photon emission computed tomography and magnetic resonance imaging, high-resolution optical imaging has appeared, among which near-infrared fluorescence imaging attention. However, even though optical molecular imaging has a wide range of applications, the tissue penetration depth is still a major obstacle to its wide application. How to achieve in-vivo depth detection is an urgent problem to be solved. [0003] The endoscopic detection method has the advantages of controllable detection depth, which can effectively solve the problem of tissue penetration depth. Through the method of the invention, the fluorescent position can...

Problems solved by technology

[0004] At present, the single-spectral video imaging system is common on the market. This system has the disadvantages of single imaging spectrum and incomplete information. Multispectral imaging can effectively overcome the above shortcomings.

However, most of the current multi-spectral imaging systems still use a single imaging device, using the filter wheel for multi-spectral switching, and using the same imaging device time-sharing, which has great limitations in video imaging effects
