An Introduction to CT Scan Image Artifacts

Greg Lehmann

Principal X-ray Engineer


There is no denying that a high resolution industrial X-ray Computed Tomography (CT) system is indispensable to any cutting-edge analysis lab that specializes in either non-destructive or destructive analysis techniques. However, one thing that can set back even the best CT analyst is when there are irritating CT image artifacts obscuring the areas that you are most interested in evaluating for defects.

Dual Tube CT Systems Offer Incredible Versatility

Chris Damhof

Global Channel Sales Representative


A recent and growing trend in the Industrial X-ray and Computed Tomography (CT) marketplace is a Dual Tube X-ray/CT System; a system which integrates both a Microfocus and Minifocus tube in the same cabinet. Dual Tube systems can scan a broader variety of products, ranging from small parts requiring high resolution all the way up to large, high-density samples.

Training & Technique Development

Eric Nokk

Technical Support Specialist/Trainer


Developing a good scan technique can take time and practice. When I’m out training new customers, I see a lot of common practices that could be improved upon, so I’ve put together a couple of useful technique development tips.

Replacing Digital Radiography Imaging with High Speed Computed Tomography

Brett Muehlhauser

R&D Technical Fellow - ASNT Level III


With the advances in CT, comes the opportunity to perform very high-speed CT scans of some products. The CT scan can quickly provide a 3D view of all indications as well as their location within a product. With a 3D data set, automatic software routines can be applied with true 3D acceptance criteria applied to assisted and automatic defect recognition (ADR) routines.

North Star Imaging’s recent robotiX development incorporates the proven technology of industrial robots into our standard line of Digital Radiography (DR) and Computed Tomography (CT) equipment. The goal of this development is to improve system automation as well as incorporate flexibility for the user.

How can 2D and 3D X-ray Imaging Help with Additive Manufacturing?

Sheng Yue

Service and Applications Engineer


Additive manufacturing (AM), sometimes referred to as 3D printing, is believed to be one of the greatest opportunities of our era and has the potential to completely change many business landscapes in the coming years and decades. There are still constraints and challenges in AM that need to be tackled by the combined efforts from scientists, engineers, and decision makers. During this process, with the help of X-ray imaging products and expertise...

Preventive Maintenance of Industrial X-ray System – A Must!

Stephanie Vinger

Service & Technical Training Manger


Industrial X-ray imaging is commonly used as part of design validation and quality control processes across many industrial applications including Aerospace, Automotive, Electronics, Medical, Pharmaceutical, Military and Defense. Similar to medical doctors and specialists checking for cracks and fractures in bones, industrial radiographers and manufacturing engineers use X-ray images to check for cracks and flaws or defects that are not visible to the human eye from the outside of the products being manufactured.  X-ray images are acquired by placing a product/object on a stage between an X-ray tube and X-ray…
