Abstract

The invention discloses an imaging system of an endoscope.According to the system, one end of a first switch is connected with red laser and the other end of the first switch is connected with a first controllable decorrelation device to serve as a first channel; one end of a second switch is connected with a green light source and the other end of the second switch is connected with a first controllable decorrelation device to serve as a second channel; one end of a third switch is connected with a blue light source and the other end of the third switch is connected with a third controllable decorrelation device to serve as a third channel; the first channel, the second channel and the third channel are connected with a mixer, and mixed signal light is output; the first controllable decorrelation device in the first channel is not enabled, output signal light is used for laser speckle imaging, a laser speckle angiography image is generated, output signal light of the second channel and the third channel is used for narrow-band light imaging, and a narrow-band light image is generated.The imaging system of the endoscope breaks through narrow-band light imaging depth, detects the angiemphraxis condition, and improves the capacity of recognizing blood vessel depth information.

Description

technical field [0001] The invention relates to the technical field of endoscope clinical function imaging, in particular to an endoscope imaging system. Background technique [0002] With the development of science and technology, a series of new endoscopic techniques are applied clinically. The NBI narrow-band imaging developed by Olympus Medical Systems Corporation of Japan has created an unprecedented advantage for the early detection of patients with nasopharyngeal tumors. [0003] In the human body, the main pigment of mucosal tissue is hemoglobin. Hemoglobin has a peak absorption capacity for blue light and relatively weak absorption for green light. Compared with conventional endoscopes, NBI technology uses narrow-band filters to filter out red light, leaving green light and blue light with center wavelengths of 540nm and 415nm respectively. Since the narrow-wavelength light does not cover all the visible light spectrum, the depth of reaching the mucosa is differe...
