【Abstract】 New approaches of reconstruction algorithm in low frequency current field are proposed, which includes Quasi-Newton, Bulirsch-Stoer extrapolation and local area accelerating convergence meth-ods. These new methods make it possible to improve the precision as well as computation speed dramat-ically in the reconstruction calculation. Intensive simulation results demonstrate that these new approaches are effective.更多还原
