The ultrasonic computed tomography (UCT) as a combination of the ultrasonic sensor and the tomographic reconstruction technique based on the filtered back-projection (FBP) was applied to investigate the cross-sectional distributions of gas holdups in a 16 cm diameter bubble column. The gas-liquid dispersion system of air-water was used. Measurements of gas holdups obtained by using UCT are compared with those obtained by bed expansion method. Generally, the trends of UCT measurement are correct but the agreement remains qualitative.
