Abstract :
In this paper, a new algorithm of image reconstruction for gamma ray tomography (GRT) systems is presented. There are several approaches to image reconstruction process. The most common algorithms in GRT are iterative algorithms. The proposed software is based on the Iterative Least Square Techniques algorithm. The software generates automatically a weight matrix for the chosen setup. Experimental results are shown.
