1. A system comprising:

  • a stereoscopic optical see-through head mounted display;

    a computing system configured to receive preoperative, intraoperative or preoperative and intraoperative image information of the physical spine of a patient and to generate a three-dimensional (3D) image of the spine of the patient,one or more markers configured to be attached to a bony structure within a target portion of the physical spine of the patient,wherein the computing system is configured to register the image information of the physical spine in a common coordinate system,wherein the computing system is configured to register the one or more markers in the common coordinate system,wherein the computing system is configured to generate a 3D stereoscopic display by the optical see-through head mounted display based on the 3D image of the spine,wherein the computing system is configured to track movement from a first position to a second position of the physical spine during surgery,wherein the computing system is configured to track the location and orientation of the optical see-through head mounted display in the common coordinate system,wherein the computing system is configured to adjust in real time the 3D stereoscopic display based on the location and orientation of the optical see-through head mounted display,wherein the computing system is configured to adjust in real time the 3D stereoscopic display based on the tracked movement from the first position to the second position of the physical spine,wherein the computing system is configured to superimpose the 3D stereoscopic display on the target portion of the physical spine visible directly through the stereoscopic optical see-through head mounted display, andwherein the first and second positions of the physical spine of the patient are different.
