A leading technology in the medical field since the 1970s, CT scanning is now taking its rightful place as a powerful observational tool in the industrial realm. A CT scan is a three-dimensional density map of any object that can be penetrated by the beam. The CT scan is generated from 2D projection images of the part onto a digital detector array (DDA), or from single rows of CT slices from a linear diode array (LDA). Once these images have been reconstructed, CT analysis software allows users to virtually slice the object in any direction, allowing them to measure internal structure and flaws. Adoption of this technology has enabled users to visualize internal structures in ways that previously could only be done by destructive methods. CT scanning has become an important tool for many research, industrial, and safety critical applications where the user needs to “see” inside an object without destroying the object in the process.
