Abstract

The 3D microfocus x-ray tomography is one technique of nondestructive testing used in the most different areas of science and technology, given its capacity to generate clean images (practically free of the unsharpness effect) and high resolution reconstructions. The unsharpness effect minimization and space resolution improvement are consequences of the focal spot size reduction in the x-ray microfocus tube to dimensions smaller than 50 micrometers . A problem normally found in the industrial area is the characterization of system parts with similar complex architectures to the bone structures. In the medicine, these structures are quantified through morphologic and topologic parameters such as: volume to volume ratio, area to volume ratio, connectivity, anisotropy and derived parameters, all obtained currently by means of the tomography system and in an automated way. In this work, the results of the complex object characterization are presented (ceramic filter) using 3D tomography system for parameter extraction.
