Zusammenfassung:	Methods, devices and systems for three-dimensional location of the disposition of a sensor coil in a subject including are disclosed. The systems include an array of three or more quadruplet drive coil sets, where each quadruplet drive coil set include at least four discrete drive coils, at least one moveable sensor coil configured to provide one or more sensor coil response signals, a first system component providing AC drive signals to energize the discrete drive coils, a second system component for receiving the one or more sensor coil response signals from the at least one moveable sensor coil, and a processor configured to determine a sensor coil disposition of the at least one moveable sensor coil in the subject relative to the quadruplet drive coil sets based on the one or more sensor coil response signals.
