Abstract
Systems and Methods for Detecting Magnetic Markers for Surgical Guidance Methods and systems for detecting a magnetic marker for guiding a surgeon to a region of interest during a surgical procedure comprising generating a driving magnetic field having a cyclic pattern comprising two or more successive periods of time, the driving magnetic field having a substantially constant, non-zero amplitude during each of the successive periods of time, and the amplitude of the driving magnetic field during at least one of the periods of time being different from the amplitude of the driving magnetic field during at least one other of the periods of time; detecting a response magnetic field; selecting at least one signal from a plurality of sensed signals, each of which corresponds to the response magnetic field detected during a respective one of the successive periods of time of each cycle; determining a detection signal corresponding to the magnetic marker using the at least one selected signal; and generating an output signal (e.g. an audio or display signal) based on a strength of the detection signal.
