Abstract

The invention discloses an augmented reality near-infrared fluorescence navigation system and method. The system comprises a near-infrared fluorescence navigation device, which is used for exciting and capturing a fluorescence signal, converting the fluorescence signal into a fluorescence image, and processing the fluorescence image and then generating a projection image, and comprises an excitation light source, an optical filter group, an imaging lens group and a spectroscope; and a projection module, used for receiving the generated projection image and generating projection light accordingto the projection image, wherein the generated projection light passes through the spectroscope, and is imaged on an observation tissue after being focused by the imaging lens group. Through the projection technology, invisible near-infrared fluorescence is visualized, the reality enhancement effect is achieved, and the problem that traditional intraoperative navigation equipment needs to repeatedly observe a display image and check the position of an actual biological tissue fluorescence signal is solved.

Description

technical field [0001] The invention relates to the technical field of internal fluorescence imaging, in particular to an augmented reality near-infrared fluorescence navigation system and method. Background technique [0002] Fluorescence imaging technology is increasingly used in surgery. It can highlight the target tissue marked by contrast agent in real time during the operation, and provide the operator with position information of blood supply or tumor, lymph and other anatomical structures. At present, fluorescent camera systems on the market usually capture fluorescent signals by using the original camera, and display the fluorescent images directly on the medical monitor, or display them on the monitor after image processing such as fusion with white light images. for dissection. However, in open surgery, repeated observation of the monitor image and checking of the actual biological tissue position causes great inconvenience to the operator, which is not conducive...
