ABSTRACT
It is certainly safe to say that for any computed tomography (CT) scanner “the system is more than the mere sum of its components.” The surprisingly large variety of industrial CT (iCT) scanners that we encounter today brings about the demand to classify them into a limited number of groups, in order to allow the users of these machines to better compare their results. Yet, to date, there is no complete manifest which can assign a well-defined system group to each existing scanner, and there are new scanners being developed and built every year that do not fit into any of the, even provisory, schemes. Therefore, this chapter will try to make the desperate attempt to provide a new larger set of system groups which—to our belief—are categorized by clear definitions and encompass almost any of the existing iCT scanners worldwide (see Section III, Chapter 45, for a description of industrial CT).
