Process analysis and application summary of surgical navigation system

In recent years, with the rapid development of computer image processing technology, medical image technology and location tracking technology, computer-aided navigation system helps doctors to determine the best surgical path through preoperative diagnosis, operation path planning, registration and intraoperative navigation, which makes the operation more accurate, rapid and safe, and opens up a new field for the development of surgery. In this paper, the key technologies, process analysis, function realization and clinical application progress of surgical navigation system are briefly summarized. Finally, this paper also makes a prospect for the development trend of surgical navigation technology.
