    摘要： 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

    摘要： Improved methods and apparatuses for imaging during medical procedures in accordance with various embodiments of the present invention include use of an image correction algorithm. In various embodiments, an original image of a region of interest where a medical procedure occurring along a particular axis will be performed is created with a beam emitter and a generally planar detector. Due to the emitter not being aligned orthogonal to the detector, the original image will be skewed. Using a known location and orientation of the detector, a location and orientation of the 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 perform the medical procedure while viewing an accurate corrected image in real-time.
