Part Geometry Considerations when Performing Computed Tomography

Abstract

The process in setting up an inspection technique using computed tomography (CT) can appear as being intrinsically simplistic. However, in some cases, the part geometry can complicate the method in how to achieve a balance between image quality throughout a volumetric part where symmetry does not exist. As the complexity of an inspection piece increases, additional considerations are needed in order to obtain the best possible information during the acquisition and reconstruction process. The manner in which the part is orientated can have significant impacts in the achieved contrast and spatial resolution components of the data. This paper is designed to provide a general understanding on these impacts and how to assess certain situations or setup consideration prior to finalizing a technique and performing a complete CT examination of the item.
