Abstract

A computational procedure, based on the boundary element method, has been developed in order to evaluate the electric field induced in a body that moves in the static field around an MRI system. A general approach enables us to investigate rigid translational and rotational movements with any change of motion velocity. The accuracy of the computations is validated by comparison with analytical solutions for simple shaped geometries. Some examples of application of the proposed procedure in the case of motion around an MRI scanner are finally presented.
