Three-dimensional brassiere design for electrical impedance tomography and numerical conductivity reconstructions in EIDORS

Abstract

We present the design of a novel three-dimensional sensing head with a hemispherical geometry which could be embedded in a brassiere for electrical impedance mammography. We also include some preliminary three-dimensional conductivity reconstructions inside a hemispherical domain which contains two inclusions with conductivities three times (or more) greater than a constant background, thereby replicating tumours in a human breast. EIDORS is used both for obtaining the simulated voltages at the passive electrodes induced by trigonometric current patterns applied at the active electrodes on the surface of the domain and for image reconstructions.
