Tomography simulation and reconstruction tools applied in the evaluation of parameters and techniques

Abstract

-In this paper we introduce a tomography platform consisting of a new set of programs written in ANSI C++ to help researchers to develop and to evaluate tomography simulation/reconstruction based on the Direct Fourier Method. We applied these tools in the evaluation of tomographic techniques. We describe and compare two techniques to overcome the inferior image quality due to the inherent artifacts of the Direct Fourier Method: the increase of the zero-padding factor and the resampling grid density factor.
