Description

Computed tomography (CT) is a radiographic method that provides an ideal examination technique whenever the goal is to locate and size volumetric detail in three dimensions. Because of the relatively good penetrability of X-rays, as well as the sensitivity of absorption to density and atomic number of matter, CT permits the nondestructive physical and, to a limited extent, chemical characterization of the internal structure of materials. Also, since the method is X-ray based, it applies both to metallic and nonmetallic specimens, solid and fibrous materials, and smooth and irregularly surfaced objects. X-ray CT provides quantitative, readily interpretable data and enables the inspections of structures that are not amenable to any other nondestructive evaluation technique. As a result CT has become well established as an inspection, evaluation, and analysis tool[1].
