METHOD AND APPARATUS FOR MAGNETIC INDUCTION TOMOGRAPHY

Publikation: SchutzrechtPatentForschung

Abstract

A method and an apparatus for magnetic induction tomography, in which an object with inhomogeneous passive electrical properties is exposed to an alternating magnetic field by excitation coils located at different positions, from which receiver coils located at different positions pick up AC signals which contain information concerning the electrical conductivity and its distribution in the object, and images of the spatial electrical properties in the interior of the object are reconstructed from the amplitudes and phases of the received signals, whereas the measurement is carried out at least 2 frequencies and an additional perturbation of the coils and/or the field geometry so as to determine a correction factor with which it is possible to widely eliminate spurious signals generated by changes of the geometry during the object measurement.
