Why CT?

The Most Advanced Technology for 3D Inspection

Whatever it is you’re making, industrial computed tomography (CT) scanning— when combined with data analysis and visualization capabilities of Volume Graphics software—provides the final word on quality assurance and the supply of competitive products to your customers. By accurately representing both outer surfaces and inner structures, CT offers the unique possibility of getting a full understanding of your product's quality, whether it's an engine block or solder joints on printed circuit boards.

Because CT reconstruction produces a complete representation of a component in 3D based on a large number of 2D X-ray images, CT allows you to answer even the most complex questions about the external and internal structures of a component and its material properties. The process of CT scanning is fast, sensitive, reliable, non-contact, and non-destructive. You can apply it at any stage of production, from prototyping to testing inline on the shop floor. The variety of potential applications for industrial CT data analysis is broad and continually expanding. 

The voxel is key to the CT scan. When an X-ray beam’s high-energy photons pass through their target, some are absorbed while others scatter, but the remaining photons strike the detector screen opposite the X-ray source. They then energize the (two-dimensional) pixels there in proportion to the density of the material being scanned as well as its thickness and attenuation values, generating a series of grayscale images. Software then reconstructs those millions of pixels into three-dimensional voxels, which make up a comprehensive, three-dimensional visualization of the scanned object. Yet to get measurements, find defects, create meshes, or perform simulations, you need the advanced analysis and visualization software provided by Volume Graphics.

With its fully integrated CT reconstruction function, Volume Graphics offers a seamless connection from the CT scanner to the comprehensive analysis and measurement functions of its software. Moreover, the software works with different CT systems from various manufacturers. Most major CT system providers sell Volume Graphics software together with their hardware. In addition, we rely on a worldwide network of distributors to serve our customers around the globe.

The Most Advanced Technology for 3D Inspection

A More Efficient Look Inside

Analyze Faster and Cost-Effectively with Volume Graphics Software

Like many of our customers, you too can save time and money by using industrial CT. This highly precise, non-destructive technology looks inside your products and finds defects that would otherwise remain hidden when using other inspection methods. However, industrial CT can only reveal its full potential when combined with the right software. Volume Graphics software is your key to unlocking this potential. Customers use our software on objects small and large, simple and complex. It works on parts made of metal, plastic, and composite materials—or all of them together. 

Performing analysis tasks directly on voxel data not only opens up possibilities that go way beyond conventional destructive or other non-destructive methods—it also comes with notable efficiency benefits.*

Inspection Costs Reduced by 50%

An Austrian automotive supplier reduced costs by around 50% after introducing industrial computed tomography (CT) as a measurement tool. Measurements using conventional optical and tactile inspection methods took 450 man-hours for the initial acceptance alone and destroyed the part in the process. Industrial CT provides insight into virtually all features of the part without destroying it—and at lower costs. With the help of CT data and the macro and batch functionality of VGSTUDIO MAX, the same process only took 100 man-hours with only 80 more man-hours needed for final acceptance.

Inspection Costs Reduced by 50%

This automotive supplier went from slice sectioning to using industrial CT-based metrology to inspect its plastic connectors—and thereby reduced the time needed for first article inspection from 75 to 12 man-hours while simultaneously improving measuring accuracy. This increase in speed was achieved in part by using the highly efficient measuring template functions of Volume Graphics software to inspect several hundred individual features of each connector.
