A complete MRI RF simulation has at least two parts involved: S-parameter optimization including frequency tuning, impedance matching and channel decoupling, and RF field generation. Previous EM-Circuit co-simulation work used every port data for field synthesis. In this abstract, the speeding factor, or the CPU/GPU time reduction factor, of the co-simulation method against the traditional broadband calculation, is present. We also compared the accuracy of field synthetization from every port data, vs. from every channel data, and propose a highly automatic optimal simulation flow that offers best field accuracy, minimum computer disk space and memory requirement, and fast data processing.
