3D CT X-RAY

3D X-Ray Computed Tomography and Inspection

nikon-xt-h-225st
The Nikon XT H 225 ST is a X-ray CT system that permits non-destructive 3D x-ray imaging of parts. It is invaluable for examination prior to, or instead of, physically sectioning or destructively testing components. CT scanning can provide internal and external three-dimensional representation of parts.

Typical Applications:

  • Material/manufacturing defects in engine turbine blades, castings and other aerospace components
  • Examination of fire debris/ fire evidence in industrial accidents
  • Failures in microelectronics, lithium-ion batteries, mobile phones, shavers, e-cigarettes & watches
  • Electric motors, transformers, circuit boards, bond wires, microwaves
  • Damage assessment in automotive and aesospace composite parts
  • Failures in Household appliances, gas valves, sensors
  • Inspection of Filters in plumbing/RO Systems
  • Evaluation of medical devices or drug delivery systems
  • Prosthetic and Implant research
  • Catheters, pace makers, teeth molds, pumps and valves.

Other areas include Aircraft Component Inspection, Conventional Metallurgy, Plastics, Composites, Manufacturing, Die and Mould Applications, Fabrics/Textiles, Metal Manufacturing, Corrosion failures.

How does 3D X-ray Computed Tomography work?

Tomography stems from the greek root word tomos which references a cut, or a slice.

The components needed for 3D CT scanning are:

  1. X-ray source
  2. Rotating geometry
  3. Detector which measures x-ray intensity attenuation via scintillation events

X-ray images are captured at specific intervals when the part is rotated 360 degrees. The series of x-ray images (slices) are reconstructed to create a 3 dimensional model of the part. The 3D model can be examined using Volume Graphics software, where internal details of the component (porosity, defects, cracks, misalignment) can be detected without the need for destructive examination.

We are the only engineering laboratory in Southern California that offers this non-destructive examination technique, the results of which are carefully analyzed by registered professional metallurgical, materials, and mechanical engineers with 30+ years of experience. Some of the parts and products that we have examined are shown in the example images in the 3D CT X-ray drop down menu.
