A direct reconstruction method, termed as the dbar method for electromagnetic tomography (EMT) is introduced. It is suitable to reconstruct distributions with high permeability and low conductivity as well as small size distributions of high conductivity. By using the dbar method, the permeability/conductivity distribution in any part of the region of interest can be obtained directly and independently...
A factorization method was introduced to electromagnetic tomography (EMT) in this paper. Compared with the traditional methods based on the sensitivity theorem, the proposed method can generate the reconstructed images directly. Neither matrix inversion nor iterations is needed in the reconstruction process. The reconstruction process is simple, as the test function is calculated according to the...
A direct reconstruction method for electromagnetic tomography (EMT) is introduced. It is suitable to reconstruct the distributions with high permeability and low conductivity. By using the proposed method, the permeability distribution in any part of the region of interest can be obtained directly and independently. Simulated data for EMT with sixteen coils were obtained in two dimensions. Neither...
