摘要

摘要研究了聚焦超声与低频磁场在神经磁刺激中的相互作用。模拟结果表明，当超声功率密度为200瓦/平方厘米时，激发所需的阈值磁场仅为0.25特斯拉左右。结果表明，这种新型的非血管型功能性神经肌肉刺激仪(FNS)在临床上对高空间分辨率的要求可能是有用的。

Ultrasonically focused neuromagnetic stimulation

Abstract The Interaction of focused ultrasound and magnetlc fields at low irequencles for neuromagnetlc stlmulatlon Is studled. Slmulatlons show that excitation requtres a threshold magnetlc fleld of only about 0.25 tesla for an ultrasound power denslty of 200 watts/cm2. The results indicate that thls new nonlnvaslve type of Functlonal Neuromuscular Stlmulatlon (FNS) mlght cllnlcally be useful when hlgh spatlal resolutlon Is requlred.
