Abstract: This document discusses, among other things, a system for guiding a medical instrument within a body of a subject. The system includes at least one magnetic emitter coupled to the medical instrument. The system also includes a plurality of magnetic sensors configured to be placed on the subject and sense at least one magnetic field generated by the at least one magnetic emitter. The system associates a position of each of the plurality of magnetic sensors with an average anatomical representation of the subject. The system also determines a position of the medical instrument relative to the average anatomical representation and the plurality of magnetic sensors. Finally, the average anatomical representation and a representation of the position of the medical instrument relative to the average anatomical representation is displayed for a user.

Abstract: This document discusses, among other things, a system for guiding a medical instrument within a body of a subject. The system includes a generic anatomical representation of at least a portion of the subject, a processing device, and a display device communicatively coupled to the processing device. The processing device is configured to determine a position of the medical instrument relative to the generic anatomical representation based on a position of the medical instrument relative to the subject. The display device configured to display the generic anatomical representation and a representation of the position of the medical instrument relative to the generic anatomical representation.
