The first part of this article introduced the basic concept of digital X-ray imaging, its components, and the commercial principles of such capital investment. Several metrics to analyze and compare processes and technologies were discussed and explained. The most important key performance indexes are overall equipment effectiveness, as a metric to describe the process efficiency, and return of invest (ROI), as a purely commercial metric to determine the feasibility of an investment. Now that the process and commercial factors are covered, we are able to move towards the even more important technical factors. It is important to keep in mind that when we are talking about nondestructive testing (NDT) equipment, quality is always the highest priority. This section of the article will provide a guideline on how to approach an investment into a new X-ray inspection system in a structured manner. Nowadays, NDT managers have a vast choice on the global equipment market, and it is easy to make unfavorable choices that lead to severe consequences in defect detectability or efficiency.
