Abstract

A research on application computed tomography to quality inspection of brass alloy has been done. The aim of the research was to study the capability of computed tomography system with source radiation isotope I-131 in order to mapping different quality of any type of brass alloy and study on the influence of activity of isotope I¹³¹ to the reconstructed image has been done. The inspection has been done by scanning three type of brass alloy, and comparing to the metal Cu and Zn which are the fundamental substances of brass alloy. The quality of brass alloy was identified through the profile of absorption of radiation and the distribution value of linear coefficient attenuation (μ) on the image and image contrast. The influence of activity isotope I-131 was studied by performance through the sinogram and reconstructed image. The result showed that the good quality of brass alloy have highest absorption of radiation than the bad quality of brass alloy, which were represented by the higher value of μ. From the visual observation on the reconstructed image, it showed that the higher activity of isotope I-131 would be used on the scanning process, the sharper sinogram contrast and reconstructed image contrast.
