Abstract

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.

Description

technical field

[0001] The invention relates to a surgical navigation system and method, in particular to a multispectral image fusion surgical navigation system and method with adjustable angle and position reflecting mirrors. Background technique

[0002] With the development of digital image processing, pattern recognition and other technologies, vision-based medical navigation technology is gradually favored by medical workers for its precise characteristics. The C-arm surgical navigation system has wide application value and application prospect in orthopedic surgery and other fields. The research on this field abroad is earlier, and special software for it has appeared in plastic surgery, spinal surgery, etc. Canada's Millennium Research Institute conducted market research and forecasts on image-guided surgical systems in the United States and Europe: in 2002, the market share in the United States was $1.43 billion, while in Europe it was $784 million; in 2003, it was...
