title: New reconstruction method of magnetoacoustic tomography with magnetic induction.
abstract: Image reconstruction is the key problem of MAT-MI. At present, there are certain problems for the images reconstruction methods which based on the divergence of Lorentz force, therefore, a new reconstruction method which based on the Lorentz force instead of its divergence is proposed in this paper. The singularity on the interface can be avoided, and it is possible to reconstruct the conductivity of imaging object directly without boundarypeak- noise on the reconstruction images. In order to test the validity of the new method, models of different structure were analyzed through numerical analysis, and the availability of the method was demonstrated.
