A method and system for registering volumetric scan data of a patient surgical site with actual patient position are disclosed. In practicing the method, position data relating to (i) the x,y,z coordinates of a detector screen in fixed coordinate system, and the x,y, coordinates of patient features on the screen are used to determine the x,y,z coordinates of the patient features in the fixed coordinate system. These coordinates are then matched with the coordinates of the same patient features taken from pre-op scan data, e.g., CT scan data, to place the CT scan data in the fixed coordinate system.
