N2 - Behaviors of micro bubbles and droplets have been analyzed by tomography methods such as an algebraic reconstruction technique (ART) and a multiplicative algebraic reconstruction technique (MART). In this study, the size, location and shape of bubbles and droplets have been calculated. This technique can be used for ejection of micro droplets or analysis of bubble behaviors in a micro channel. Two tomography methods have been compared to obtain more accurate results of the two-phase flows. Initially, a bubbly flow and an annular flow have been investigated by cross-sectional views using computer-synthesized phantoms. Then, reconstruction of three-dimensional density distributions of phantoms with two and three micro bubbles have been accomplished by the MART method which provided the better results for the two-dimensional reconstructions accurately to analyze the bubble behaviors in the micro flow.
