Displacement-current phase tomography (DCPT) is a process tomographic technique originally proposed to overcome the limitations of electrical capacitance tomography (ECT) for two-phase flows where one phase is electrically conductive such as water. Both DCPT and ECT are 2D cross-sectional imaging techniques. In this paper, two new developments based on DCPT are described. First, we describe the extension of DCPT to perform direct volumetric imaging. Second, a new method for fluid flow velocimetry (3D velocity profiling) based on volumetric DCPT is proposed. The simulation and the experimental results are provided to demonstrate the proposed techniques for the imaging of water-dominated vertical flows.
