Abstract: Methods and systems for determining and mapping a location of a distal end region of an elongate shaft. An illustrative method may comprise obtaining data from an accelerometer located in the elongate shaft adjacent a distal end thereof, determining a length of the elongate shaft inserted into a body from a reference point, merging the accelerometer data and the length of the elongate shaft to localize the distal end region of the elongate shaft, reconstructing a line of travel of the medical device within the body, and superimposing the reconstructed line of travel over an image of an anatomy of the patient.
