摘要

建立了电磁场与人体头部的相互作用模型,并采用有限元数值模拟方法计算了1.5 T磁共振成像设备工作频率为64 MHz时的涡流。由于组织结构的复杂性,需要更详细地解释建模结果。分配给模型中每个元素的不同组织属性以表的形式给出。最后,对结果进行了讨论。

Analysis of possible imperilled areas in human head during magnetic resonance imaging
The interaction of electromagnetic field and human head is modelled and the eddy currents are calculated at 64 MHz, the operating frequency of a 1.5 T MRI device by numerical finite element simulation. The complexity of the tissue structure imposes a need for explaining the modelling results in more detail. The different tissue properties assigned to every element in the model are given in the form of a table. Finally, the results are discussed.<>
