    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.

    Abstract: A method for detecting a marker in a body, comprising receiving an input signal from a probe, where the input signal is generated by a probe in response to detecting a marker signal from the marker; determining a marker proximity value based on the input signal, the marker proximity value corresponds to a distance between the probe and the marker; generating a feedback signal for output by a user interface device based on the marker proximity value, and outputting feedback signal, wherein range of the marker proximity value is divided into predetermined distance bands; and wherein at least one parameter of the feedback signal, or a rate of change of the at least one parameter of the feedback signal in relation to marker proximity value, is varied discontinuously at a boundary between at least two adjacent bands. The feedback signal may be an audio signal and/or a haptic signal.

    Abstract: A method and apparatus for preparing tissue of interest in a patient for possible excision by surgery. In one embodiment, the method comprises the steps of: removing a biopsy sample from the tissue of interest; placing a magnetic marker at the biopsy site; performing a pathology analysis of the biopsy sample; and if the pathology analysis indicates that the tissue of interest should be removed, locating the tissue for surgery using a magnetic detection probe. In one embodiment, the marker comprises magnetic nanoparticles in a bioabsorbable matrix. A system for preparing tissue of interest in a patient for possible excision by surgery. In one embodiment, the system includes a magnetic marker and magnetic detection probe system.
