Abstract

A medical navigation system is provided for registering a patient for a medical procedure with the medical navigation system using fiducial markers. The fiducial markers are placed on the patient prior to a 3D scan and the fiducial markers each have a target for use with a tracking system. The medical navigation system comprises a 3D scanner, a tracking system, a display, and a controller electrically coupled to the 3D scanner, the tracking system, and the display. The controller has a processor coupled to a memory. The controller is configured to: receive 3D scan data generated by the 3D scanner representative of a 3D scan of at least a portion of the patient, the 3D scan including the fiducial markers visible by the 3D scanner; load from the memory saved medical image data, the saved medical data including preoperative image data saved during a previous scan of at least a portion of the patient; receive position data from the tracking system based on the target for each of the fiducial markers; and perform a transformation mapping to create a single unified virtual coordinate space based on the 3D scan data, the position data, and the medical image data, and updating registration data of the medical navigation system based on the transformation mapping.
