CT-Assisted Engineering and Manufacturing
X-ray computed tomography (CT) is an important and powerful tool in industrial imaging for obtaining shape and dimensional information of industrial parts. It also serves to provide digital models of parts for inputs to new and emerging technologies in the manufacturing industry that have begun to embrace CT-assisted engineering and design. Since a large number of objects encountered in industrial CT are made either of a single homogenous material or a few homogenous materials, algorithms for discrete tomography should, in principle, yield CT images whose resolution and dimensional accuracy are superior to CT images obtained by conventional algorithms. This in turn should result in significant improvements in the accuracy of boundaries extracted from CT images for the creation of digital models of a large class of parts of interest in CT-assisted manufacturing. This chapter looks at some important applications in CT-assisted engineering and manufacturing that can benefit from the techniques of discrete tomography, and discuss some of the technical challenges faced in extracting boundaries with the degree of accuracy demanded for engineering and manufacturing applications.
