Electrical impedance spectroscopy (EIS) is a potential, noninvasive technique to image women for breast cancer. Studies have shown characteristic frequency dispersions in the electrical conductivity and permittivity of malignant versus normal tissue.

Using extensive simulations, we have investigated the behaviour of finite element image reconstruction for electrical impedance tomography in the presence of inaccuracies likely to exist in real measurements. This study characterizes reconstruction w

We have deployed a recently completed spectroscopic electrical impedance tomography (EITS) imaging system in a small series of women (13 participants accrued to date) in order to investigate the feasibility of delivering EITS breast examinations on a

We have recently built and tested a 32 channel, multi-frequency (1 kHz to 1 MHz) voltage mode system to investigate electrical impedance spectroscopy (EIS) imaging. We completed a series of phantom experiments to define the baseline imaging performan

Four model-based imaging systems are currently being developed for breast cancer detection at Dartmouth College. A potential advantage of multimodality imaging is the prospect of combining information collected from each system to provide a more comp

Electrical impedance imaging of the breast is potentially promising but faces a number of challenges related to improving the sensitivity and reliability of the technique. Electrode models have been accepted as important components of image reconstru

Our previous system covered the frequency range of 0 to 1 MHz. In this new design we propose to cover the range from 0 to 10 MHz. The higher frequencies have forced us to reconsider several design decisions in view of both the physics of the problem

Isaacson, Cheney and Seager have demonstrated that simultaneously applying trigonometric patterns of current to a circular electrode array optimizes the sensitivity of EIT to inner structure. We have found that it is less desirable to measure voltage

Miniaturization and reduction of design and production costs of electronics is at the forefront of today's technological efforts. Ground based applications have been the forerunner of this trend. It is proposed that a space analog be created. A modul
