摘要:

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.

关键词: 磁共振电阻抗成像, 磁共振电流密度成像, 各向同性, 各向异性, 正交各向异性

Abstract:

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.

Key words: magnetic resonance electrical impedance tomography (MREIT), magnetic resonance current density imaging (MRCDI), isotropy, anisotropy; orthotropy
