摘要 在建立虚拟人体脑部模型的基础上,推导了阻抗法的计算公式,计算出了人脑的SAR。数据通过Matlab软件进行图像处理,得到了在准静态磁场作用下人脑的三维SAR分布。将计算结果与有限差分方法的计算结果进行了比较,在计算小物体时阻抗法具有简单、无需严格设置边界条件和计算速度快等优点。 Based on a fictitious model of human head, the calculation equations using impedance method and SAR distribution of human head were gotten. Picturing the datum by Matlab, 3-Dimension SAR of human head would be found. Comparing with the results of FDTD, the impedance method is easier, faster and doesn＇t need consider the strict boundary conditions.
