A STUDY OF RECONSTRUCTION ALGORITHM ON INSPECTION OF FOREIGN SUBSTANCE IN BRAIN BY LOW FREQUENCY CURRENT FIELD
低频电流场颅内异物检测技术重建算法的研究

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.
