The B0 eddy current, which shifts the temporal B0 and is harmful to MR Image quality, hasn’t been analyzed in detail before. In this work, we provide a FEM-circuit co-simulation method for this problem and the result clearly shows that main superconducting coil plays an important role in shaping the B0 EC time constant and thus to include them in model is necessary for making accurate prediction.
