Abstract: Magnetic induction tomography, highly promising imaging technique
for medical purposes, applies a magnetic field from an exciter to induce eddy
currents in the object of low conductivity, and the magnetic field from these
is then detected by a sensor. The induced eddy currents are proportional to the
conductivity distribution. This paper deals with the solution of the
fundamental inverse problem existing in magnetic induction tomography, which
consists in the reconstruction of the eddy currents distribution basing on the
magnetic field measurements. The problem has been solved by the Tikhonov
regularization method. The choice of the regularization parameter and the
accuracy of the proposed method have also been discussed.
Keywords: Magnetic induction tomography, image reconstruction, Tikhonov regularization method
