Abstract
This paper suggests the implementation of an algorithm that improves the X-ray tomographic reconstruction quality of a parallel acquisition geometry by adding virtual projections to the reconstruction process in order to increase the angular resolution of the measuring device, as in the case of CT scanners. The suggested method is based on an estimated calculation of virtual projections using the zero-padding properties. The obtained results show a significant reduction of the noise effect on the reconstructed image and a remarkable quality improvement despite the use of a rudimentary tomographic device.
