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

A spinal image generation system based on ultrasonic rubbing technique, wherein the spinal image generation system creates ultrasonic rubbing on basis of two-dimensional spinal ultrasonic images;

• the ultrasonic rubbing matches with a digital medical image by characteristic contours, and a personalized spinal surface topographical map, which updates in real-time with a posture of a patient during surgery, is established;
• the spinal image generation system comprises an acquisition unit and a processor;
• the acquisition unit acquires two-dimensional spinal ultrasonic images, wherein said two-dimensional spinal ultrasonic images comprise surface characteristic contours of a vertebra surface corresponding to a real-time intraoperative posture of the patient under surgical condition;
• the processor processes said two-dimensional spinal ultrasonic images comprising the surface characteristic contours to generate the ultrasonic rubbing, and matches the ultrasonic rubbing with the digital medical image through the surface characteristic contours to establish the personalized spinal surface topographical map, which updates in real-time with the real-time intraoperative posture of the patient under surgical condition;
• wherein the two-dimensional spinal ultrasonic images comprise ultrasonic echoes from deep muscle tissue in a spinal region and from the vertebra surface;
• said vertebra surface comprises spinous process and transverse process;
• the ultrasonic rubbing is a personalized three-dimensional spinal image having spatial location information of the patient and continuously updates in real-time consistent with position change of the patient.
