Abstract
A surgical navigation system is disclosed including a camera that is fixedly attached to a patient. The camera space merges with the patient space and thereby eliminates the need for a separate patient tracker. The surgical navigation system calculates the position of a surgical tool with a tracking device in view of the camera and shows on a display device the position of the surgical tool with respect to the patient superimposed and in correlation with a scan image of the patient.
