Industrial Computed Tomography

3D Inspections
On Non-Destructive Testing

Industry-focused businesses understand the importance of testing their equipment parts. Preventative maintenance and new product development efforts hinge on finding the flaws and weaknesses of important components before something goes wrong – failure is not an option in the aviation and nuclear industries, for instance. Companies subject their assets to inspection for that reason. Inspectors, usually engineers or technicians, are trained to ensure that no avoidable problem sneaks up on the critical equipment that keeps industry running.

Non-destructive testing is the preferred family of analysis method for customers; if the subject passes its inspection, putting the part back into use is a far more attractive prospect than losing it entirely.

Strengths and Uses of Industrial Computed Tomography

Industrial Computed Tomography is one of the most comprehensive and powerful NDT methods available. It uses X-rays to build an image of the test material as if it had been sectioned in layers. An X-ray emitter takes multiple projections of the subject while rotating around it, which are received by a DR imaging panel.

The projections capture the subject from every angle and can be assembled into a single 3D model for easy manipulation and study. Because it is a composite made of many images, the model shows features beneath the exterior surface of the subject with an incredible amount of detail — far more clarity than afforded by conventional radiography methods. CT also employs the precision of 3D scanning methods, allowing the computer to measure internal components and flaws volumetrically by comparing the scanned model to its CAD model.

Computed Tomography is a multifaceted inspection method because it gives multiple test results for the same amount of time and effort spent on performing one test. Because this scanning method includes features of both X-ray and 3D inspections, technicians can measure both coating and surface material thickness readings on the subject without having to perform a further ultrasonic thickness test.

Though this technology has been available to the medical field for decades, it was a costly and cumbersome prospect for use in other industries. Due to recent improvements in complementary technology, such as computers with greater processing power and more sensitive DR imaging panels however, Computed Tomography has become a practical testing method for industrial inspections. Scanning test materials now takes a relatively small amount of time, whereas before the process of assembling the 3D model took hours. The improved DR imaging panels are the reason for the higher level of visual detail in each X-rayed projection.
