Originální abstrakt

This paper introduces new possibilities within two-dimensional reconstruction of internal conductivity distribution. A new algorithm for the conductivity reconstruction was developed. This algorithm utilizes the internal current information with respect to corresponding boundary conditions and the induced magnetic field measured outside the object. A series of computer simulations has been conducted to assess the performance of the proposed algorithm within the process of estimating electrical conductivity changes in the lungs, heart, and brain tissues captured in two-dimensional piecewise homogeneous chest and head models. The reconstructed conductivity distribution using the proposed method is compared with that using a conventional method based on Electrical Impedance Tomography (EIT). The acquired experience is discussed and the direction of further research is proposed.
