Abstract：
Based on Born approximation, the reconstruction of the flaw shape in the cement cylinder was studied experimentally. The experimental results showed that it could reconstruct the flaw shape in cylindrical structure by home-made piezoelectric longitudinal transducer and Born approximation theory, the size of the reconstructing flaw was almost the same to the actual size of the flaw. The relationship between the structural characteristics of the flaw and the scattering amplitude was established. The study showed that it has good corresponding relationship between the structural characteristics of the flaw and the scattering amplitude, the shape of the flaw could be reconstructed by using the scattering amplitude.
