Problems solved by technology

[0005] The purpose of the present invention is to provide a fluorescence navigation system based on photometric feedback and its intraoperative fluorescence navigation adjustment method, aiming to solve the problem of blood perfusion caused by the existing fluorescence imaging system using the camera to automatically adjust the exposure parameters according to the current target brightness. The real fluorescence brightness change process cannot be accurately presented, and quantitative analysis cannot be performed

Abstract

The invention discloses a fluorescence navigation system based on photometric feedback and an intraoperative fluorescence navigation adjustment method thereof. A beam splitter is additionally arrangedon an imaging light path, a photoelectric detector detects the intensity of excitation light which enters the imaging light path and is reflected by tissue, a distance is obtained through operation and fed back to the system, and exposure parameters of a camera can be adjusted in real time, so that the system truly reflects the fluorescence change condition in the blood perfusion process under the condition of adapting to fluorescence imaging at different imaging distances.

Description

technical field [0001] The invention relates to a fluorescence navigation system, in particular to a fluorescence navigation system based on photometry feedback and an intraoperative fluorescence navigation adjustment method. Background technique [0002] Near-infrared fluorescence contrast technology is widely used in the fields of organ transplantation, plastic reconstruction, and trauma care. This technology can use the change of fluorescence intensity to display the blood perfusion of anastomosis or other parts in real time. By intravenously injecting near-infrared fluorescent contrast agent into the patient, the contrast agent enters the target area along with the blood flow, and as the content of the contrast agent in the target area increases, the fluorescence intensity will also increase. Continuous observation of the changes in fluorescence can determine the blood perfusion of the site. But when it is observed close to the tissue, the illumination area is small, th...
