Simulation of Electrode for Dual-Modality Electrical Resistance Tomography and Ultrasonic Transmission Tomography for Imaging Two-Phase Liquid and Gas

Accurate multiphase flow measurement of gas/liquid, liquid/solid and liquid/liquid flow is still challenging for researchers in process tomography. The reconstructed images are poor particularly in the center area because of ill-posed inverse problems and limited of measurements data. Dual-modality...
