| Abstract: | A new imaging modality combining magnetic resonance imaging(MRI) technology and electrical impedance tomography(EIT) technology is introduced,which is called magnetic resonance electrical impedance tomography(MREIT).The key technique called magnetic resonance current imaging is described.Meanwhile,the characteristic analysis of the hardware system is given and recent development and several main models and algorithms have been reviewed.At last,the main problems and developing direction in MREIT are discussed as well. |
