  • Title: Fast MRI coil analysis based on 3-D electromagnetic and RF circuit co-simulation.
    Author: Kozlov M, Turner R.
    Journal: J Magn Reson; 2009 Sep; 200(1):147-52. PubMed ID: 19570700.
    Abstract:
    To accelerate the analysis of a multi-element MRI coil, a two-way link is used between radiofrequency (RF) circuit and 3-D electromagnetic (EM) simulation tools. In this configuration, only one 3-D EM simulation is required to investigate the coil performance over a range of different tunings, saving considerable computation time. For the purpose of 3-D EM simulation, the coil feed networks and trim capacitors are substituted by 50Omega ports. The entire coil was tuned in the RF circuit domain, and the near-field profiles of the electric and magnetic field components were then calculated, together with the specific energy absorption ratio (SAR) maps in the 3-D EM domain.
