摘要

The application of the industrial gamma computed tomography (CT) apparatus, using ~(75)Se (148-329 keV) as the gamma source, to evaluate the reconstructed image quality by projection steps is presented. In this article we are intended to focus on influence of view and position variations on reconstructed image quality experimentally. The results show that increasing number of Ar (positions) has inverse and direct relationship with RMS contrast and number of reconstructed image pixels.
