摘要
Magnetic induction tomography of biological tissue is used for reconstructing the conductivity distribution kappa = sigma + jomegaepsilon or changes Deltakappa in a human body by measuring the perturbation DeltaB of an alternating magnetic field B-0. The aim is to simulate the eddy current problem in magnetic induction tomography for biomedical applications by symmetric tetrahedral edge finite elements of second order. The method is validated by measurement data from a representative experiment, and numerical results of an edema in a human head are presented.
