Calculation and Estimation of Acoustical Length from Ultrasound Signal for Diffraction Tomography

There are considerabel interests in the use of acoustical lengths for characterization of scattered data required in diffraction tomography. In this paper, we present two new methods, calculation of acoustical lengths by Hibert transform and estimate on of integrated values on the scan lines from calcualted vales. These techniques offer insight into the acquisition of projection data in diffraction tomography. The validity of the proposed methods has bee confirmed by computer simulation.
