Compliance Consultants worked on a new technology known as an Electrical Impedance Scanning (EIS) system. This technology creates a pattern using electrical impedance tomography (EIT). A plurality of electrodes is provided in electrical contact with the body around the periphery of the body. A first electrical input signal is applied to at least one of the electrodes over a first time period, and a second electrical input signal, which is preferably in an inverted form of the first.

The measured impedance to the flow of the current reflects the electrical properties of the tissue elements in the current path.


When an area of the breast becomes malignant there is (a) an increase in the volume of fluid in the region and (b) the cell membrane becomes electrically porous, both changes resulting in a decrease in electrical impedance in the area.


Electrical changes associated with cancer, therefore, can be regarded as a marker that can be detected by a system capable of measuring electrical impedance throughout the breast.
