Abstract:
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.
