Industrial measurement is transitioning from traditional external measurement to internal non-destructive analysis and full-scale measurement. X-ray CT technology relies on tomography and advanced measurement and analysis software to clearly, accurately, and intuitively display the internal structure, material composition, and defect status of the tested object in the form of two-dimensional cross-sectional images or three-dimensional three-dimensional images without damage. Metrological CT is a CT system with high measurement accuracy, also known as X-ray coordinate measurement system. With the help of metrological CT technology, you can successfully obtain all internal and external structures and perform dimensional measurements with just one scan.
