Computed Tomography

What is Computed Tomography, and how does it work?


Computed Tomography or CT is a process which utilizes X-Ray equipment to produce 3D representations of components both externally and internally. CT scanning has been utilized in many areas of industry for internal inspection of components such as Aluminium castings to check for porosity. Some of the key uses for CT scanning have been flaw detection, failure analysis, metrology, assembly analysis, and reverse engineering applications. CT scanning is also employed successfully in the imaging and conservation of museum artifacts.

CT is a technology that uses computer-processed X-Rays to produce tomographic images (virtual 'slices') of specific areas of the scanned object, allowing the user to see what is inside it without cutting it open. In its simplistic form, it’s rather like taking a loaf of bread, slicing it, and then being able to inspect each slice for features without having physical to cut it. Digital geometry processing is then used to generate a three-dimensional image of the inside of an object from a large series of two-dimensional radiographic images taken around a single axis of rotation. Medical imaging is still the most common application of X-Ray CT, but it is now becoming increasingly prevalent in NDT.

CT produces a volume of data that can be manipulated in order to demonstrate various part features based on their ability to block the x-ray beam. Although, historically, the images generated were in the axial or transverse plane, perpendicular to the long axis of the part, modern scanners allow this volume of data to be reformatted in various planes or even as volumetric (3D) representations of structures.

Euroteck Systems work with Procon X-Ray GmbH to provide a number of CT system solutions.

Procon X-Ray GmbH unlike many of their competitors in the CT market adopt a very flexible approach to their CT systems. Customer requirements are always first and foremost in the consultancy/enquiry stage. If a certain aspect of the CT machine isn’t to your liking, then this can be changed so the customer has a CT system built to their specific requirements.
