Abstract :
A number of studies have pointed to a link between the presence of breast cancer and a larger than normal tissue electrical admittance in the affected area. This phenomenon could make electrical impedance-based imaging a practical asset to breast cancer screening. In this paper image reconstruction algorithms are developed and evaluated for use with an impedance-based imaging system constructed at The George Washington University. The system, which is targeted for use in breast cancer screening, is profiled. Computer simulation-based results for the two reconstruction approaches are shown and evaluated.
