Paper Abstract

Acoustic diffraction tomography (DT) is an inversion scheme that can reconstruct the spatially variant acoustic properties of a scattering object. In this work, we develop and investigate a novel reconstruction algorithm for reconstructing separate images of the density and compressibility fluctuations of nonviscoelastic scattering objects. The reconstruction algorithm is derived by identifying and exploiting tomographic symmetries and the rotational invariance of the problem. The proposed reconstruction algorithm is implemented numerically and demonstrated by use of computer-simulation studies.
