Abstract

The invention provides an endoscope imaging and laser speckle imaging integrated imaging system. The endoscope imaging and laser speckle imaging integrated imaging system comprises an endoscope imaging subsystem, a laser speckle imaging subsystem and image integration processing equipment, in the endoscope imaging subsystem, a CCD (charge coupled device) detector and an LED (light emitting diode) light source are both arranged on a first end of an endoscope hose pipe, and are electrically connected with a first image processing device; in the laser speckle imaging subsystem, a laser assembly is arranged on the first end of the endoscope hose pipe, a second image processing device is arranged on the downstream of a light path of the laser assembly, and the first image processing device and the second image processing device are electrically connected with the image integration processing equipment. The endoscope imaging and laser speckle imaging integrated imaging system has the advantages that by adopting the technical scheme, the problems of limitation of laser speckle imaging by the optical imaging illuminating structure and failure to in-vitro scanning and imaging due to small photon penetration depth in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular, to a fusion imaging system of endoscope imaging and laser speckle imaging. Background technique [0002] Laser speckle contrast imaging technology is a technology that obtains the moving speed of particles by analyzing the scattering characteristics of moving particles to coherent laser light. Laser speckle contrast imaging can perform real-time full-field imaging of the microcirculation blood flow of living organisms with high temporal and spatial resolution. Due to the advantages of non-contact, non-invasive and fast imaging, laser speckle imaging technology is very suitable for imaging measurement of blood microcirculation. Microcirculation parameters such as vessel diameter, vessel density, blood flow velocity and blood perfusion can be measured using laser speckle technology. By examining the structure of microcirculation blood vessels, microcirculation function and ...
