Industrial CT Scanning Enjoys Many Analytical Benefits Over 3D Scanning and Other Non-CT Diagnostic Services

Computed Tomography (CT) scanning has been a fixture in the medical industry since the 1970s. It is an imaging technology that takes multiple X-rays of a subject along a rotating axis. The X-rays are caught by a detector (called a DR imaging panel), which is always positioned across from the X-ray generator with the subject between them. A computer processes the raw data yielded by the detector into an interpretable scan in a process called tomographic reconstruction. Each of these scans shows a cross-sectional view of the subject as if it had been cut in half. This allows for a detailed look at the inside of the subject without physically harming it. Computers can assemble all of the CT scans into a single 3D model, which is easily viewed and manipulated by technicians. Programs can measure specific features from the scan, such as voids or cracks, volumetrically and with a near-microscopic level of precision. One can see how beneficial this technology has been for doctors diagnosing everything from a tumor in the brain to a blockage in the circulatory system.

Recent developments in supporting technology (faster computers with greater processing power, increased sensitivity of DR panels, etc.) have made CT scanning practical for industrial use. This is an exciting development for the inspection industry because of CT scanning’s benefits over older inspection methods.

CT scanning, for instance, provides a far clearer image with greater detail than does older radiography imaging; it also boasts added features such as producing a 3D model and displaying multiple views from different angles. CT scanning also enjoys more versatility than does regular 3D imaging. CT results show the inside of the test material for defect-measuring purposes while the former only shows surface details. CT scanning is beloved by the inspection community for its many uses – one CT inspection can yield results for thickness measurements, defect analysis, failure analysis, and other tests.

Further highlights of CT scanning as a non-destructive testing method include:
  • It is now possible to scan parts with awkward shapes that radiography methods couldn’t handle
  • Impeccable detail afforded by CT helps failure analysis efforts as well
    • Information from many images makes up a single model
    • Precise enough to highlight the tiniest of structural defects
  • 3D component is a boon to metrology
    • Only practical method for measuring flaws in internal components in a non-destructive test
  • Works well with additive manufacturing (3D printing) for defect analysis
  • Computer detects flaws by comparing models
    • Both Part-to-CAD and P2P comparisons
  • Can convert 3D models to usable CAD data
    • Don’t have to build them from scratch
    • Reverse engineering made easier
    • Measure geometric dimensioning and tolerance (GD&P)
  • 4D Imaging
    • Create simulation of part working in a live-use scenario
    • Examine stresses and forces exerted on components during operation

Now, the same diagnostic technology widely used in the medical field is available to aerospace companies looking for voids in critical parts and manufacturing corporations in need of failure analysis services in the wake of a product recall. Industrial CT scanning services are being offered by few inspection companies at the moment, which is why it is notable that Applied Technical Services, Inc. has added CT scanning to its already long list of services rendered.
