Nowadays, ultrasound imaging is widely used for medical applications. However, the current method in the ultrasound scanner is based on a pulse echo method. This method is difficult to reconstruct the structures which are smaller than the incident wavelength. Ultrasound tomography using the inverse scattering technique could accomplish this matter. We can identify strange tumors because when the ultrasonic signal passes through the object, the transfer speed will change. Born iterative method (BIM) and Distorted Born iterative method (DBIM) are preferred because they could build a linear relationship between the measured ultrasonic signals with the ultrasonic speed difference. This paper proposes an improved solution to DBIM using interpolation technique to ensure both rapid convergence and minimum calculation in order to improve the quality of ultrasound tomography.
