AN INVERSE PROBLEM FOR CONDUCTIVITY IMAGING WITH REGULARIZATION
介质导电率成像数值反演的正则化方法

Magnetic Resonance Electrical Impedance Tomography(MREIT)is a new medical imaging technique.The basic idea of MREIT is to reconstruct the medium conductivity using the internal magnetic flux information.This paper considers the numerical realization of the well-developed harmonic-B_z algorithm for noisy input data.By constructing the minimizer of the Tikhonov functional in terms of the spline function,we propose a stable realization of harmonic-B_z algorithm.The error estimates are provided.Finally,numerica...
