ABSTRACT
This chapter provides a new larger set of system groups which are categorized by clear definitions and encompass almost any of the existing industrial computed tomography (iCT) scanners worldwide. Contrary to the medical scanner, standard iCT machines rotate the object, allowing for a much simpler computed tomography (CT) system setup requiring only one sample rotation stage. While the X-ray system components in macro-CT are strictly limited to conventional or rotating anodes, as well as to large area detectors, the mechanics of such systems sometimes deviate a lot from the typical axial scan. Micro-CT scans may be applied to investigate glass fiber plastic composites or aluminum castings, in search of cracks and pores. In view of the less stringent requirements on the X-ray source, the overall system costs for a detector-based sub-μ CT system are significantly lower than for equivalent source-based systems.
