A probe instrument using room-temperature sensor(s) that can measure magnetic susceptibilities variations. The instrument includes room temperature magnetic sensors, and detects the sample, that is the tissue response to an applied field coil. The sensors that can be used include magnetoresistive, fluxgate...http://www.google.fr/patents/US6418335?utm_source=gb-gplus-shareBrevet US6418335 - Ferromagnetic foreign body detection using magnetics
