Zusammenfassung:A method and system to use an augmented reality device in a surgical procedure. The method includes rendering, on the display of the device, a model of a patient reference object; in response to receiving input, moving the model of the patient reference object in an augmented reality coordinate system; determining that the model is aligned with the patient reference object in real world space when viewed through the display and, based on that determination, identifying a first transform from the augmented reality coordinate system to a navigation coordinate system used by an optical navigation system for tracking the patient reference object; subsequently transferring patient image data from the navigation coordinate system to the augmented reality coordinate system using an inverse of the first transform; and displaying the patient image data on the display to augment a real world view of a patient.
