The global industrial CT market is at a nascent stage in terms of market adoption. CT is identified as a favorable solution for quality inspection and control, and so, many OEMs and research organizations are pursuing the development of CT systems and broadening their applications. They are mostly used for inspection of components within products, which are either inaccessible or have certain hidden features.

Jujhar Singh, a lead analyst at Technavio, specializing in research on embedded systems sector, says, “CT is used for analysis of faults and inspection of interior surfaces, as well as parting surfaces of assembled parts. Compared with CMMs or optical measurement systems, CT equipment can conduct analyses and measurements of structures and capture unknown outlines of specimens, like cavities, something which optical sensors cannot offer.”

Improved measurement resolution

Industrial CT technology has seen rapid improvements in recent years. A few single CT slices would previously have taken hours to generate, but now, it is possible to completely reconstruct 3D models having billions of voxels in nearly 30 to 45 minutes, which is still slow by industry standards, but a significant improvement from four to five years ago.

“Numerous applications like reverse engineering, rapid prototyping, and 3D metrology have become possible. In that regard, industrial CT has become a very competitive technology for 3D scanning. 3D CT reconstruction can also be transformed into a surface model,” according to Jujhar.

Increasing focus on micro-focus tubes

For a microCT system, the microfocus X-ray tube is an essential component, as the spatial resolution of CT images, theoretically, is determined by the size and stability of the X-ray focal spot of the microfocus X-ray tube. However, factors such as voltage fluctuations, temperature changes, and mechanical vibrations may cause degradation to X-ray focal spot's size and stability.

These developed microfocus X-ray tubes can help reduce unfavorable effects such as the electron beam trajectory swinging and the beam size changing for the micro-focus X-ray tube, allowing for lesser CT image artifacts, which are created by the X-ray focal spot shift and change of size, thereby producing image clearer and more accurate.

Scanning of larger components

Industrial CT facilitates analysis of faults, material, and density analysis or the examination of completeness and coordinate metrology in 3D. The CT scanning allows manufacturing plants to significantly reduce new product ramp up (an increase in firm production ahead of anticipated increases in product demand) and troubleshooting times, thereby optimizing production parameters, avoiding recalls, detecting problems at an early stage, and avoiding a scrap.

The CT systems consist of dust-protected radiation protection cabinet with integrated rotating scanning devices and sample transportation system for moving components across the scan ring. As a result, CT scans of parts can be done, which range between 900 mm in length and 500 mm in diameter, which was not possible for larger capacity some years ago.

The key vendors are as follows:

  • General Electric
  • Nikon Metrology
