Abstract: The time-varying drive field in MPI is subject to magnetostimulation and specific absorption rate (SAR) limits. For frequencies up to 50 kHz, magnetostimulation is the dominant safety concern [1-2]. In this work, we investigate both the frequency and duration dependence of magnetostimulation limits for the drive field in MPI.
