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.

频率和脉冲时间对MPI磁刺激极限的影响

MPI的时变驱动场受磁刺激和比吸收率(SAR)限制。对于高达50 kHz的频率，磁刺激是主要的安全问题[1-2]。在这项工作中，我们研究了磁刺激极限对MPI驱动场的频率和持续时间的依赖性。
