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.
已经开发了一种基于边界元法的计算程序，以便评估在 MRI 系统周围静态场中移动的物体所产生的电场。通用方法使我们能够研究具有任何运动速度变化的刚性平移和旋转运动。通过与简单形状几何形状的解析解进行比较，验证了计算的准确性。最后提出了一些在 MRI 扫描仪周围运动情况下应用所提出程序的示例。
