Abstract
Improved methods and apparatuses for inserting pedicle screws in accordance with embodiments of the present invention include an image correction algorithm. In various embodiments, an original image of a region of interest of a patient including a pedicle is created with an X-ray emitter and an X-ray detector. Due to the X-ray emitter not being aligned orthogonal to the X-ray detector, the original image will be skewed. Using a known location and orientation of the X-ray detector, a location and orientation of the X-ray emitter provided by a position monitoring system, and the original image, a processing system can execute the image correction algorithm to provide a corrected image to allow a surgeon to properly insert a pedicle screw along the axis of the pedicle while viewing an accurate corrected image in real time.
