Spinal image generation system based on ultrasonic rubbing technique and navigation positioning system for spinal surgery

摘要

A spinal image generation system based on the ultrasonic rubbing technique, comprises an acquisition unit and a processing unit. The system generates the ultrasonic rubbing based on two-dimensional spinal ultrasonic images. The image needs to include surface characteristic contour of the vertebra structure. The ultrasonic rubbing matches with a digital medical image through characteristic contour. After matching, a personalized spinal surface topographical map is established, which keeps real-time updating consistently with the intraoperative posture of the patient under surgical condition. A positioning and navigation system for spinal surgery based on the spinal image generation system, comprising a navigation module and the image generation system above. The navigation system can acquire a personalized spinal surface topographical map, which keeps real-time updating consistently with the intraoperative posture of the patient under surgical condition.
