Abstract

Numerical simulation is a valuable tool for the study of magnetic susceptibility artifacts from metallic implants. A major difficulty in the simulation lies in the computation of the magnetic field induced by the metallic implant, A new method has been designed and implemented to compute the magnetic field induced by metallic objects of arbitrary shape. The magnetic fieldis expressed pointwise in terms of a surface integral, Efficient quadrature schemes are proposed to evaluate this integral. Finally, the method is linked to an artifact reconstruction model to simulate the images. Magn ResonMed 45: 724-727, 2001. (C) 2001 Wiley-Liss, Inc.
