Abstract
A method for use during a procedure on a body. The method generates a display representing relative positions of two structure during the procedure. The method includes the steps of storing an image data set in memory, the image data set representing the position of the body based on scans taken of the body prior to the procedure; reading the image data set stored in the memory, the image data set having a plurality of data points in known relation to a plurality of reference points for at least one of the two structures; placing one or more magnetic field sensors in known relation to the reference points of the two structures; generating a magnetic field; detecting the magnetic field with the magnetic field sensors; ascertaining the locations of the sensors based upon the magnetic field detected by the sensors and processing the locations of the sensors to generate a displaced image data set representing the relative position of the two structures during the procedure; and generating a display based on the displaced image data set illustrating the relative position of the two structures during the procedure.
