The basis for developing projection tomographic reconstruction algorithms has been the
assumption of straight-line ray path propagation. But, in the case in which propagation …

In this paper, diffraction tomography is presented as an inverse problem of an
inhomogenous differential equation obtained from the Helmholtz equation in terms of a …

This paper reviews diffraction tomography as it applies to electromagnetic and acoustical
imaging. We have discussed the various approximations that are used and shown their …

Since the papers by WOLF [1], DEVANEY [2] and others, there has been considerable
interest in the reconstruction of a scattering potential (ie a function or object which generates …

The basis for developing projection tomographic reconstruction algorithms has been the
assumption of straight-line ray-path propagation. But in the case in which propagation …

Scalar linearized inverse scattering has recently found a unified treatment within the
framework of diffraction tomography in either frequency or angular diversity. The linear …

A reconstruction algorithm is derived for parallel beam transmission computed tomography
through two-dimensional structures in which diffraction of the insonifying beam must be …

In many imaging applications, the wavelength of the illuminating wave is comparable in
scale to the structural features of interest. Hence, the scattering and diffraction effects have to …

A variational principle for the scattering amplitude is applied to obtain a relationship, in the
Fourier domain, between the scattering potential and the scattered field recorded over a …

The possibility of incorporating evanescent wave components of the scattered field into
diffraction tomographic reconstruction algorithms offers new options to improve the …
