ABSTRACT
This paper is concerned with a still emerging medical imaging modality called Electrical Impedance Tomography. This process involves constructing images of the electrical impedance of the body’s interior based upon measurements of voltage and current made at the body’s surface. The electrical impedance accounts for both resistivity and permittivity. This paper shows how permittivity can be exploited to improve the performance of an electrical impedance imaging system. The explicit use of the independent information in the data due to the permittivity will enhance a system’s ability to distinguish objects in the interior of a body.
