This engineering/physical chemistry study develops an analytical model and uses computer simulations to describe the electric field in oxide films during thermal metal oxidation. It reports that the electrostatic potential drop across the bulk oxide is often limited to about kBT/e, suggesting most of a larger overall…

This engineering study presents an optimization framework to design RF pulses for parallel transmission MRI with the goal of minimizing SAR. Using computer simulations of a 4-channel system, the authors report significant SAR reduction while maintaining excitation pattern quality and without increasing pulse…
