摘要
如图1b所示，对于同一组受试者，横向磁场的平均磁刺激阈值比轴向磁场低约3倍(ΔBmin = 26 mT-pp vs. 78 mT-pp)， τc值相当(265 μs vs. 243 μs)。此外，横向视场的受试者间偏差百分比(13%)明显小于轴向视场(28%)。对于横向场和轴向场，数据趋势很好地由双曲振幅与频率曲线模拟，如图1c所示。
Comparison of magnetostimulation limits for axial and transverse drive fields in MPI
As shown in Fig. 1b, the mean magneto stimulation thresholds for the transverse field was approximately 3 times lower than the axial field (ΔBmin = 26 mT-pp vs. 78 mT-pp) for the same set of subjects, with comparable τc values (265 μs vs. 243 μs). In addition, the percentage deviation across subjects was significantly smaller for the transverse field (13%) than the axial field (28%). For both transverse and axial fields, the data trends were well modeled by the hyperbolic amplitude vs. frequency curve, as demonstrated in Fig. 1c for a single subject.
