se Use of impedance techniques in breast-mass detection By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A device is described for measuring electrical characteristics of biological tissues with one or a plurality of electrodes and a processor controlling the stimulation and measurement in order to detect the presence of abnormal tissue masses in the breast and determine probability of tumors containing malignant cancer cells being present in a breast. The device has the capability of providing the location of the abnormality, at least to the quadrant. Either single or multiple source electrodes can be used. Either palpable lumps can be evaluated or screening or breasts, whether with palpable masses or not, can be accomplished. The method for measuring electrical characteristics includes placing electrodes and applying a voltage waveform in conjunction with a current detector. A mathematical analysis method is then applied to the collected data, which computes spectrum of frequencies and correlates magnitudes and phases with given algebraic conditions to determine mass presence and type.
