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 field is 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 Reson Med 45:724–727, 2001.

We present a new simulation code for electrostatic waves in one dimension which uses the Vlasov equation to integrate the distribution function and Ampère's equation to integrate the electric field forward in time. Previous Vlasov codes used the Vlasov and Poisson equations. Using Ampère's equation
