Problems solved by technology
At this time, it is necessary to repeatedly adjust the brightness of the LED light source, or adjust the parameters such as the gain and exposure time of the fluorescent camera, which brings inconvenience to the operation
At the same time, the high temperature brought by the excessive power of the LED light source will burn human tissue
[0004] To sum up, the AR fluorescence surgical navigation system has inconsistencies in the distance of fluorescence imaging due to the large variation of the working distance, which affects the image quality and brings inconvenience to clinical use.

The invention provides an AR fluorescent surgical navigation system and method, and relates to the technical field of surgical diagnos. The AR fluorescent surgical navigation system is characterized by comprising: an illumination module, which is used for illuminating tissue; a camera module, which is used for receiving first fluorescence emitted by the tissue and generating an image signal; a depth module, which is used for generating depth information; and an image processing module, which is used for receiving the image signal and the depth information, generating a fluorescence image according to the image signal, and adjusting the exposure parameter of the camera module according to the depth information, or adjusting the exposure parameter of the camera module according to the depth information and the brightness of the fluorescence image. The AR fluorescent surgical navigation system and method provided by the invention have the advantages that image brightness is stable and uniform, and frequent manual adjustment of exposure parameters is not needed.
Description
Technical field [0001] The present application relates to the field of surgical diagnosis, and in particular, there is an AR fluorescent surgery navigation system and method. Background technique [0002] Modern medical imaging system is an indispensable tool for clinical surgery. In open surgery, the AR fluorescent surgical navigation system can accumulate the lesion tissue structure and function information provided by the image to the actual scene, strengthen the organizational structure of the tissue captured by the image device in the actual biological tissue of the human eye. , Functional molecular developing signal, etc. [0003] In order to meet ergonomics and give a good experience, the AR fluorescent surgery navigation system ranges from 0.5 meters from the subject to 1.2 meters. Clinical use, the organ tissue in the surgical field of view is difficult to fluoresce in a large working distance. If the system sets the gain and exposure time parameters of the fluorescent c...
