The iNSIde View

In traditional cone-beam X-ray Industrial Computed Tomography (CT) scanning, an x-ray source is used to penetrate various objects. During the acquisition process, x-rays pass through the object, ultimately reaching the X-ray detector and producing a two-dimensional radiographic image. A typical CT project can generate thousands of 2D images which are then collected and used to generate a 3D volumetric reconstruction of the internals and externals of the object (see figure 1).

Preventing system downtime is one of the most critical aspects to ensuring productivity and manufacturing efficiency as well as continued innovation with research and development. Having system issues due to a lack of regular maintenance can greatly hinder production and even bring it to a complete stop.

In the correct application, vorteX can provide significant advantages over conventional cone beam CT. Understanding these advantages greatly expands the versatility of the CT system.

Have you ever wondered about how modern science in today’s industries safeguard our lives? Let’s take a closer look at nondestructive testing and how it aids in that process by using industrial digital X-ray scanning for early detection to gauge a parts quality and integrity.

North Star Imaging filled 200 seats at the St. Michael Cinema, near our headquarters in Rogers, Minnesota on May 22nd-23rd for our 2018 Technical Symposium event. Every day these technical experts look for ways to push the limits of technology and nature. But each person using nondestructive X-ray testing has one common goal; to see beyond the surface.

X-ray computed tomography (CT) has successfully entered the field of coordinate metrology as an innovative and flexible non-contact measurement technology for performing dimensional measurements on industrial parts. It provides unique advantages compared to conventional tactile and optical coordinate measuring machines (CMMs), giving the ability to perform nondestructive measurement tasks that are often not possible with any other measurement technology.

Attendees saw presentations from NSI on CT scanning of additive manufactured parts as well as live demos of digital X-ray and CT scanning technology. Instron demonstrated their new Bluehill® Universal Software and ElectroPuls™ dynamic test system.

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.

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.

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.
