Abstract :
Filtered Back-Projection (FBP) is a well-known algorithm for reconstruction of tomographic images from projections. Some of FBP´s highlights are: (i) it allows agile software implementations, and; (ii) it produces images of good quality, i.e., relatively free of artifacts. Our goal is to reconstruct images from fan beam projections collected by detectors set in a linear array
