Abstract

Provided are a multi-spectral imaging endoscopic detection system and method. The multi-spectral imaging endoscopic detection system is formed by a casing, a semi-transparent semi-reflective mirror, a light source portion, an optical fiber, a micro lens, a light filter unit, a Charge Coupled Device (CCD) camera, a computer and a single chip microcomputer. By adopting the multi-spectral imaging endoscopic detection system and method, the multi-spectral imaging technology and the spectrum light splitting technology are combined, the problem of fast obtaining colored images and multi-channel spectral information in human body interior detection complex environments is solved, a spectral imaging picture in the endoscopic environment is finally obtained by adopting a time information integration method and a self-adapting exposure method, morphology features and material spectral information of human body internal organizations are reflected.

Description

technical field [0001] The invention relates to photoelectric physiological detection equipment, in particular to a multispectral imaging endoscopic detection system and detection method. Background technique [0002] Due to the characteristics of some diseases, such as strong concealment, long incubation period, difficulty in observation, and no change in in vitro characteristics, endoscopic detection devices are more and more widely used. The endoscope can enter the body to be detected through the natural orifice, and can also be inserted into the body through the incision and minimally invasive opening in the operation. Medical endoscopes are of great value to modern medical diagnosis and treatment. [0003] The traditional narrow-band imaging endoscopic detection technology was proposed and developed by Olympus Corporation. This technology can effectively observe the changes in the capillary state of the digestive tract mucosa. The narrow-band imaging endoscope filters ...
