TL;DR: All tissues and organs were reconstructed as three-dimensional unstructured triangulated surface objects, yielding high precision images of individual features of the body, which greatly enhances the meshing flexibility and the accuracy in comparison with the traditional voxel-based representation of anatomical models.

TL;DR: Numerical simulation is used to study RF heating for external fixation devices in both 1.5-T and 3-T MRI coils and it is found that changing insertion depth and screw spacing could largely affect the heating of these devices.

TL;DR: In this article, an analytical model based on an equivalent impedance circuit for effective permittivity of a composite dielectric as a function of frequency with complex-shaped inclusions is presented.

TL;DR: In this paper, the authors studied the effect of external fixation devices under MRI RF field for both 15-T and 3-T systems and found that changing insertion depth and pin spacing could largely affect the surface heating level.

TL;DR: A systematic framework for the optimization and analysis of the equivalent characteristic impedance of practical via structures using Polynomial Chaos method, which naturally leads to a rigorous methodology for EM design/control in the presence of multiple sources of uncertainty.
