摘　　要：生物电阻抗成像技术在脑功能和脑疾病检测与监护中具有潜在的应用价值,并且具有无创伤、功能性、价格低、操作简便等优点,是目前生物医学工程的研究热点。本文主要介绍了生物电阻抗成像技术在脑功能和脑疾病成像的研究现状,并着重讨论了EIT(electrical impedance tomography,生物电阻抗断层成像)、MIT(magnetic induction tomography,磁感应电阻抗成像)、MREIT(magnetic resonanceelectrical impedance tomography,磁共振电阻抗成像)、MAT-MI(magnetoacoustic tomography with magneticinduction,磁感应磁声成像)技术在成像过程中的区别及今后有待近一步解决的理论与技术难题。Biological electrical impedance imaging shows great potential application value in detection and monitoring the brain function and brain diseases, which is a novel focus in the field of biomedical engineering as the advantages of non-invasive ness, functionality, low price, simple operation etc. The application of biological electrical impedance imaging in detection and monitoring of brain function and brain diseases is introduced in this paper. It takes an emphasis on discussing the difference applications in the imaging process of electrical impedance imaging,megnetic induction tomography, magnetoacoustic tomography with magnetic induction and magnetic resonance electrical impedance tomography, but there are many theorical and technological problems to be further solved.
