An image guided surgery system to enable a surgeon to move a surgical tool into a desired position relative to a body part is provided. The system works by accurately superimposing representations of the tool being used in the surgical field over images of the body part such that real-time tool position feedback is provided to the surgeon. The system uses a fluoroscopic x-ray device to generate two-dimensional body part images, a localizing device to determine the poses of surgical tools and the x-ray device, mathematical modeling of the imaging chain of the x-ray device, and a display for displaying the images of the body part superimposed with representations of the surgical tools. A digital flat-panel x-ray imager permits fluoroscopic x-ray device to be used in any orientation without being affected by distortions due to local magnetic fields.
