Applied Current Injection and Magnetic Field Induction Simultaneously on Electrical Impedance Tomography

Ill-posed problem is an important issue arises in electrical impedance tomography. The nonlinearity of the system, lack of sensitivity, and lack of data reconstruction are the causes of ill-posed. Merging of multiple modalities adds data reconstruction, but it increasesa nonlinearities of the system. The uses of only two modalities, namely current injection system and induced magnetic field system, but with a combination of a data collection system configuration is sufficient to increase the amount of information. On the other hand, the complexity of the system and the degree of nonlinearity are not too high. Some simultaneous combination of two modalities was conducted to the rectangular object. The work was focused to identify anomalies position far away from the boundary. The results show that a decrease in errors of reconstruction in line with the addition of the number of retrieved data.
