| Abstract: | Ultrasound Computerized Tomography (UCT) has entered a new stage in the family of Process Tomography (PT) which is playing a dominating role in the field of monitoring and controlling the industrial process parameters. In this paper presented are tomographic theorems of Diffraction-Mode, Reflection-Mode and Transmission-Mode (TM) UCT, as well as the possibility of their application to the gas/liquid two-phase fluid measurement. Then the details are discussed of TM UCT method concerning the theory, system configuration and reconstructive algorithm applied to the gas/liquid two-phase fluid. Finally, the future prospects of UCT are also given. |
