Computed Tomography scan in progress
A Brief History

Computed Tomography (CT) was initially introduced as a medical imaging tool in the 1970s. The scanner consists of an X–ray projector mounted across from a DR imaging panel on a rotating axis. As the projector revolves around the subject and takes X–rays, the imaging panel picks up the raw data from those projections and sends it to the computer. That raw data is transformed into an actual image through a process called tomographic reconstruction. The image that is produced will show a cross–sectional view of the subject as if it had been cut in half – perfect for looking at a patient’s brain in a non-invasive manner. Technicians can then assemble all of the CT images together in order to create a single 3D model, which is easy to manipulate and study. Because the model is made up of so much data from so many reference points, a CT scan produces a clearer and more precise image than older radiography methods. CT has become a valuable diagnostic tool for doctors looking for things as small as a tumor or internal bleeding.

Industrial Computed Tomography

CT has many advantages over other imaging methods. Radiography, for instance, only produces a single 2D image with less visual clarity. A CT scan produces as many as thousands of 2D images compiled into one 3D model. This difference means that a CT scan of an object (as well as features such as cracks) can be measured by volume. 3D inspections, on the other hand, lack the ability to look beneath the surface of the test material – while they may render similar amounts of detail, a CT scan is able to locate and even highlight imperfections below the surface.

Versatility is another benefit afforded by CT scanning. This one method can yield results that could only be found through multiple tests otherwise. One CT scan can take thickness measurements, locate structural flaws, and measure features volumetrically. This efficiency means a faster turnaround for clients.

ATS and CT Scanning

For years, this technology was impractical for industries outside of the medical sector. With recent developments in related technology however (faster computers with more processing power, increasingly sensitive DR imaging panels, etc.), some inspection companies are finding it feasible to offer industrial CT scanning as a non–destructive testing method. Because of how new this technology is to the industrial inspection community, however, few companies are currently providing these services. Applied Technical Services, Inc. is one of those few.

ATS has delivered world–class engineering, consulting, testing, and inspection services for 50 years. Our technicians are committed to reporting the most accurate and relevant analyses to our clients in a timely manner.
