Abstract: Simultaneous measurements of X-ray projection data from several angles around a static experimental model were implemented by rotating the model between an X-ray tube and a flat plate detectorThe static model simulated a two-phase system with water and air inside, forming four bubbles at the cross-sectionThe measurement system consisted of a Model 150-I Mobile X-ray Unit operated at the potential of 150 kV, a MiniX-1 X-ray flat plate detector, and a data acquisition systemBy using the measured instantaneous projection data from different angles, the cross-sectional image was reconstructed with the established genetic algorithm based fast X-ray computed tomographic method(GA-XCT)A series of real experiments clearly demonstrated the feasibility and capability of the GA-XCT in the application of “bubbles” reconstruction compared with the conventional CT reconstruction algorithm using limited projection dataMeanwhile, the GA based image reconstruction is robust to the noise.
