Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0030] It should also be noted that the orientation terms such as left, right, up, and down in this embodiment are only relative concepts or refer to the normal use state of the product, and should not be regarded as limiting.

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 present invention relates to the technical field of medical imaging, in particular to an endoscopic imaging and laser speckle imaging fusion imaging system. Background technique [0002] Laser speckle contrast imaging technology is a technique to obtain particle motion velocity by analyzing the scattering characteristics of moving particles to coherent laser light. Laser speckle contrast imaging can perform real-time full-field imaging of microcirculatory blood flow in living organisms with high spatiotemporal 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 blood vessel diameter, blood vessel density, blood flow velocity and blood perfusion can be measured using laser speckle technology. By investigating the structure of microcirculation blood vessels, microcirculation function ...
