Use of impedance techniques in breast-mass detection
First Claim
1. A device for testing presence and tracking of benign or malignant breast masses, the device including comprising:
- a. signal generator configured to deliver simultaneous stimuli at multiple frequencies with one or a plurality of source electrodes configured for attachment where a breast joins the chest wall of a patient,b. a receiving electrode adapted for configured for attachment to the nipple of the same breast;
c. a computer program stored on a non-transient medium executed by a control system,d. the control system configured to use the simultaneously occurring multi-frequencies coherent signals applied in a sequence to each source electrode to stimulate tissue through;
e. the control system configured to use ratio-metric measurements and coherent sampling across simultaneously occurring signals in returning current from the tissue;
f. the control system configured to determine ratio measurements where the measurements examines the interaction between multiple-frequencies amplitudes and phases, not the absolute values;
g. the control system configured to use derived ratios created in clinical studies of tissue to determine a classification result of the determined ratio measurements of tissue selected from the group consisting of healthy, benign, and malignant tissue; and
h. the control system configured to use an indicator that indicates the results to the user.

Abstract
A device is described for measuring electrical characteristics of biological tissues with 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. 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.
