Innovative design and accuracy of optical and electromagnetic integrated surgical navigation system: phantom and in vivo studies

The novel optical and electromagnetic integrated surgical navigation system is demonstrated that it not only retains the accuracy and stability compared with the traditional optical navigation system, but also has high precision electromagnetic navigation function. The registration accuracy of navigation can only represent the principle error of engineering, and the overall error of the actual application of navigation system should include the system registration error, human operation error and the error of navigation special tools.
