## Abstract In this research, with a view to three‐dimensional image reconstruction, a method for tracking the coordinates of the tomographic image plane is investigated by drawing attention to the shift and variation of the speckle pattern in the B‐mode image. In this method, the shift vector in t

In order to improve the resolution of defect reconstruction for non-destructive evaluation, a new phase superposition processing (PSP) method has been developed on the basis of a synthetic aperture focusing technique (SAFT). The proposed method synthesizes the magnitudes of phase-superposed delayed
