1. A method comprising:
aligning an image data set to a two-dimensional (2D) X-ray generated image of an anatomical structure containing at least one visible marker by using data fitting to align the anatomical structure shared between the image data set and the 2D X-ray generated image;
defining a location of the at least one visible marker in the image data set using the 2D X-ray generated image; and
aligning the image data set with a patient, based in part on the at least one visible marker correlated to the image data set as referenced to the at least one visible marker that is seen on the patient through an AR headset.
