In this study, we propose a methodology to achieve consistency between EM simulation and measurement results by implementing BCI-monitoring probe system as an model. To accurately model the BCI monitoring using EM, it is necessary calculate magnetic permeability μr′(ω) μr″(ω), which change according frequency of ferrite constituting core probe. The impedance measured includes connector capacita...

PURPOSE Magnetic field homogeneity is important in all aspects of magnetic resonance imaging. A new approach to increase field homogeneity is presented that allows dynamic and adaptive control over the flow of current over a single surface using a network of actively controlled solid-state switches. METHODS Computer simulations were completed demonstrating the potential of this approach. Wire...
