1. A method for enhancement of fluoroscopic registration in real time for placement of pedicle screws, vertebral augmentation or interbody spacers/artificial discs during spine surgery, comprising:
creating, by an imaging device in a first position for lateral imaging, a lateral image of a vertebral body in which a superior endplate is at least partially visualized,
in accordance with the created lateral image, advancing a pin into the vertebral body starting in the posterior cortex and moved far enough into the vertebral body until bony purchase is obtained so that the pin is anchored,
rotating the imaging device from the first position to a second position for Anterior-Posterior (AP) imaging to obtain an AP image of a pedicle, wherein the obtained AP image renders the pin positioned in the lateral image to be neutral in a cephalad to caudad direction, and
positioning a pedicle screw, vertebral augmentation, interbody spacer, or artificial disc in or adjacent to the pedicle following a 2D contour mapping generated by manual templating or automated templating.
