摘要 我们对最新发展的阻抗成像方法——核磁共振电阻抗成像(Magnetic resonance electrical impedance tomography,MREIT)技术进行了综述,简要介绍了CT(Computerized tomography,CT)和MRI(Magnetic resonanceimaging,MRI)成像技术的基本原理,详述了MREIT技术基本理论和目前MREIT算法的发展状况,并就MREIT的发展前景及目前存在的问题进行了分析。 In this paper, a review of a new electrical impedance tomography technique-magnetic resonance electrical impedance tomography （ MREIT） is presented. Some medical imaging methods are briefly introduced. The basic theory of MREIT is given as well as its realization methods and developing status. The merits and challenges of this new trend are also demonstrated.
