Abstract: Various embodiments set forth medical devices. In some embodiments, the medical device includes an impedance bridge, an instrument head that includes one or more electrode pairs and a calibration impedance, and one or more wire pairs that couple the impedance bridge to the one or more electrode pairs and the calibration impedance. The disclosed medical devices compensate for impedance caused by extraneous factors arising from manufacturing and materials variances while measuring the impedance of tissue.

Abstract: One embodiment of the present application sets forth a method for detecting cancerous cells in a sample of excised tissue. The method includes a first subset of electrodes included in an electrode array measuring, at a first operating frequency, a first impedance of a first section of the sample. The method also includes computing a first Cole relaxation frequency for the first section of the sample based on the first impedance. The method also includes determining that the first section of the sample contains cancerous cells based on the first Cole relaxation frequency.

Abstract: One embodiment of the present application sets forth a method for predicting recurrence of cancerous cells in a patient that includes measuring, by a first subset of electrodes included in an electrode array operating at a first frequency, a first impedance of a first section of a first sample of tissue excised from the patient, computing a first Cole relaxation frequency for the first section of the first sample based on the first impedance, and generating a first prediction relating to cancerous cells in the patient based at least in part on the first Cole relaxation frequency.
