Appl. No.:

13/835380

Inventors:

William D. Gregory - Shorewood WI, US
Christopher W W. Gregory - Joppa MD, US
John R. Shell - Milwaukee WI, US

International Classification:

A61B 5/053
A61B 5/00

US Classification:

600547

Abstract:

A method for characterizing tissues within a subject as cancerous or non-cancerous includes determining the electrical properties of the subject. The electrical properties of the subject are fit to a model and a specific range of a set of characteristic frequencies of each tissue is then calculated. Each tissue is finally characterized as cancerous or non-cancerous if the specific range of the set of characteristic frequencies inside or outside, respectively, a pre-determined spread of characteristic frequencies.

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.
