Tamer S. Ibrahim1,
Electromagnetic simulations in MRI can take significant calculation (CPU) time. Not only this can dampen the progress of evaluating the performance of the coil, it renders these methods impracticable for real time applications such as multi-transmission methods. This work aims at overcoming this obstacle through developing a stable and fast implicit finite difference time domain scheme that is suitable for MRI RF calculations. Very good correlation was attained for the B1+ field distribution obtained through calculations using standard FDTD and implicit FDTD methods, and through MRI experimental measurements.
