Cherenkov endoscope system based on conical optical fiber connection and medical imaging system

Abstract

The invention belongs to the technical field of medical imaging, and discloses a Cherenkov endoscope system based on conical optical fiber connection and a medical imaging system. The Cherenkov endoscope system comprises an endoscope probe, an optical fiber image-transmitting bundle, a connecting device, a detecting device and a computing and imaging device, wherein the connecting device is a conical optical fiber and is used for connecting an endoscope with an imaging camera. The conical optical fiber is used as the connecting device for the endoscope and the imaging camera, and therefore theoptical signal loss of the Cherenkov endoscope system is effectively reduced; the Cherenkov endoscope system is simple in structure and meets clinical application requirements. The collecting rate ofCherenkov optical signals is high; the conical optical fiber is used for replacing an medical endoscope adapter to connect the optical fiber image-transmitting bundle and the imaging camera, a metalprotective bush completely wraps the conical optical fiber, in this way, the optical signal loss caused by the adapter and a coupling part is substantially reduced, the signal collection time for effective imaging of the Cherenkov endoscope is shortened, and clinical conversion of the Cherenkov endoscope is promoted.

Description

technical field [0001] The invention belongs to the technical field of medical imaging, and in particular relates to a Cherenkov endoscope system and a medical imaging system based on a tapered optical fiber connection. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: the endoscope was invented and applied in clinic as early as a hundred years ago, which greatly improved the diagnostic accuracy of digestive tract diseases. With the continuous development of science and technology, endoscopy has made great progress, but it is only morphological imaging, and the identification of anatomically similar diseases is low. Therefore, traditional white light endoscopy is not very effective in the early detection of diseases, especially tumors. With the introduction of molecular imaging and the maturity of medical imaging technology, the integration of morphological imaging and molecular imaging into endoscopic equipment h...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the prior art are: the signal acquisition efficiency of the Cerenkov endoscope system formed by connecting the ordinary medical endoscope and the EMCCD camera through an adapter lens is low, and the light signal of the endoscope system is low. The loss in the medium is too large, and its imaging takes a long time, which greatly limits the clinical application of Cherenkov endoscope
