| Abstract: | The development of EIT is summarized based on the concept and advantages of the Electrical impedance tomography (EIT) from the following three aspects: multi-frequency electrical impedance tomography (MEEIT), induced current electrical impedance tomography (ICEIT)and magnetic induction tomography (MIT). The advantages of the developing methods are expatiated and compared with the traditional EIT . The future application trend of them is pointed out. EIT is one of the key projects of biomedical engineering today. It is an ideal medical imaging technology with enticing prospect. |
