Abstract
In this paper, we consider Colton-Kirsh regularized sampling (CK-RS), holographic backprojection tomography, and diffraction tomography. The latter of these algorithms are based on the Born approximation, whereas regularized sampling is not. Numerical simulations have been performed for several different scatterer geometries and varying levels of noise in the forward data in order to quantity image quality as a function of SNR.
