Advanced 3D Scanning

Computed Tomography (CT) has come a long way since its public inception in 1972. The rapid improvement of CT and the increasing capabilities of CT scans have definitely gone hand in hand. CT scans that used to take hours, now take seconds. This increase in capabilities has led to the use of CT scans more often and in more ways than ever before. The use of CT in the industrial nondestructive testing (NDT) field is one segment that has grown tremendously in the past few years.


Industrial CT uses a series of 2D images taken at specific intervals around the entire sample. Any type of industrial CT system uses three principal components: an X-ray tube, an X-ray detector, and a rotational stage. Everything is enclosed in a radiation,
