Abstract: A method for detecting and diagnosing disease states in a body part is described. The method starts with a preparatory step of modeling the body part as a grid of many finite elements, then calculating an electrical property between two finite elements at which current from two corresponding electrodes flows through the body part. This is termed the weight (influence) of the element. With this baseline information, electrical impedance measurements made at the plurality of electrodes on the periphery of the body part can be used in a diagnostic module to calculate a Weighted Element Value (WEVal) for each element. In a preferred embodiment of invention, the difference in WEVal magnitude between corresponding elements of homologous body parts serves as an indicator of the presence of disease.

Abstract: A system and method for detecting and diagnosing disease states in a body part is described. The method is based on a set of electrical impedance measurements taken on the surface of a body part and a representation of the body part in the form of a network of impedances that would result in the same surface measurements as the actual body part. The system includes an electrical data unit for measuring electrical data of the body part, the electrical data unit having a plurality of Ne electrodes. The system also includes a network module for representing the body part by a network, the network having external nodes and internal nodes connected by current pathways. The system further includes an electrical properties module for determining electrical properties of the pathways using the measured electrical data, and a diagnosis module for utilizing the electrical properties to diagnose the possibility of disease in the body part.

Abstract: A breast electrode array and method of analysis for detecting and diagnosing diseases. In particular, the electrode array has a body, a plurality of flexible arms extending from the body, and a plurality of outer electrodes provided by the plurality of flexible arms, and a plurality of inner electrodes provided on at least one of the flexible arms and positioned partway between the body and the outer electrodes, and the outer electrodes and the inner electrodes are arranged on the arms to obtain impedance measurements between respective electrodes. Diagnostic methods based on homologous electrical difference analysis are also provided, utilizing the different topologies created by the inner and outer electrodes when taking impedance measurements.

Abstract: A system and method for diagnosing the possibility of disease by making electrical measurements in one of a first body part and a second substantially similar body part are described. The present invention balances out differences between homologous body parts that are due to natural factors unrelated to disease, such as differences in size or symmetry between left and right breasts. Once data are prebalanced, statistical analyses can be performed on the data to diagnose disease. The system includes a normalizing module for obtaining a normalizing factors database from a screening population group to account for differences in spatial separation of impedance measurements. Once a set of normalizing factors is obtained, a prebalancing factor can be obtained that can further be used to adjust raw electrical measurements. Normalizing factors are applied to a smaller subset of measurements that are likely to better represent the body part as a whole.
