Electrical conductivity imaging of tissue can potentially provide electrical property information of tissues. Here, we proposed a dual constraints based electrical conductivity imaging method to reconstruct the distribution of conductivity. The proposed method transforms the partial differential equation into an optimization problem with total variation and wavelet transform regularization terms. To evaluate the performance of the proposed method numerical simulations and phantom experiments were implemented at 3T. The results showed that the proposed method improves the accuracy of the conductivity estimate and suppress the effect of noise. The proposed method is expected to be applied clinically in the future.
