Electromagnetic tomography (EMT) sensing system with multi-excitation-modes is introduced. It can produce three excitation modes, among which the quasi-parallel excitation mode can give more independent projections than the parallel mode and produces relatively more even sensitivity distribution than the coil-pair mode. A new kind of image reconstruction algorithm based on inverse problem is proposed...
Electromagnetic Tomography technology has bright future in the two-phase flow measurement, and the study of the image reconstruction algorithm is important to improve the measurement accuracy. A new kind of algorithm based on Modified Newton-Raphson method was proposed and applied to the EMT image reconstruction for solid-gas two-phase flow measurement. The simulated reconstruction results of the...
