正交各向异性磁共振电阻抗成像问题的唯一性

摘要

We proved the uniqueness result of magnetic resonance electrical impedance tomography (MREIT) problem with orthotropic conductivity under the hypothesis that there are at least two couples of imposed electric current density which are not parallel to each other based on some eletromagnetism theorems and the result of the index theory.%利用电磁学的一系列基本定理和指标理论证明了在至少有两组互不平行输入电流的条件下,电导率分布为正交各向异性的磁共振电阻抗成像(MREIT)问题的唯一性.
