Surgery navigation system and method based on multispectral image fusion of reflecting mirror faces with adjustable angles and adjustable positions

The utility model provides a surgery navigation system and method based on multispectral image fusion of reflecting mirror faces with adjustable angles and adjustable positions. The system comprises a C-shaped arm machine frame (11), an X-ray emission bulb tube (12), an image enhancement and acquisition device (13), an image processing workstation and a liquid crystal display monitor and further comprises two parallel reflecting mirrors (14), hinges (15), reflecting mirror guide rails (16), inserting grooves, a visible light CCD camera (17), a camera guide rail (18) and a calibration body with mark points. According to the surgery navigation method, a fluoroscopic image and an image acquired by the camera have the same visual angle and frame area, late image registration and other algorithm and the calculation process are simplified, the image with the optimal visual angle can be obtained through the adjustable reflecting mirror faces, and the method can be applied to surgeries of different positions flexibly. Registration is performed on the fluoroscopic image and a visible light image before a surgery, the X-ray emission bulb tube is turned off, a visible light real-time image is used for guiding the surgery, ionization radiation to doctors and patients is reduced, and positioning accuracy and treatment efficiency are improved.
