Improving the quality of the reconstructed image based on the dynamic local mesh refinement

A new method used to improve the quality of the electrical impedance dynamic imaging is presented in the paper. It uses local refinement to change the finite element discretization while the refined areas are selected by the man and machine interaction. As a result, the accuracy and resolution of the reconstructed image are increased but the computation amount and the stability of the algorithm are maintained. Experiment validates the efficiency of the method.
