Systems for superimposing a virtual display on a physical spine

A system comprising:

• a see-through optical head mounted display, and
• a processor,
• wherein the processor is configured to generate a virtual display of a spine of a patient,
• wherein the see-through optical head mounted display is configured to display the virtual display of the spine of the patient,
• wherein the virtual display comprises a three-dimensional digital representation corresponding to at least a portion of the physical spine of the patient,
• wherein the processor is configured to receive data from an artificial neural network to superimpose the virtual display with the at least portion of the physical spine,
• wherein the data comprise a first parameter and a second parameter, and
• wherein the first parameter comprises information about an anatomic landmark, anatomic dimension, anatomic shape, a bony structure, an intervertebral disk, an image, one or more coordinates or a combination thereof, from an MRI scan,
• wherein the second parameter comprises information about an anatomic landmark, anatomic dimension, anatomic shape, a bony structure, an intervertebral disk, one or more coordinates or a combination thereof, from an x-ray.
