Abstract

Unknown electric conductivities of human tissues is a common issue in medical engineering. Electrical impedance tomography (EIT) is an imaging modality that can be used to determine these conductivities in vivo from boundary measurements. In this paper, we demonstrate that local conductivity values of different skull segments can be solved from EIT measurements with the help of a box constraint. Based on our numerical results, the accuracy of the results depended on the locations of the current carrying electrodes and the signal to noise ratio of the measurements. Particularly, the conductivity values of the skull segments that located below the current carrying electrodes were reconstructed more accurately.
