Description

Industrial computerized-tomography (CT) systems have been used to perform visual and quantitative analysis on industrial objects for several years. A tomogram is formed by placing an object between a radiation source and an arc of detectors, and rotating and translating the object to acquire many thousands of measurements through the desired cross-sectional plane. This process takes from 20 seconds to an hour, depending on the size of the object and the quality of image desired; a few minutes is typical. A complete series of closely-spaced cross-sectional tomograms can provide a complete three-dimensional map of the object, but is time-consuming and therefore often not cost-effective.
