Computed Tomography (CT) is a technology that allows 3D reconstruction of test parts. This allows advanced analyses of the error shape, position and distribution. Depending on the application slower high-accuracy scans or fast scans are available.
Classic digital radiography (DR) cannot deliver any depth information of defects in X-ray images. As it is a purely two dimensional technology the viewer can just tell that there is an error, but never how deep it is inside the material. Nevertheless, in some applications it is a big difference if the error is close to the surface or deep inside the part. Another interesting metric is the exact defect-volume, which is impossible to determine in 2D images.
To retrieve the reconstruction data, the X-ray system needs to be capable to perform the synchronized mechanical movement. Our XRH222 for example has precise and programmable drives to acquire all needed images. Physical X-ray hardening through hardware filters is applied through a filter unit. In parallel the image quality needs to be enhanced in the background to further increase the quality and reduce artifacts. The intermediate result are thousands of X-ray images that will be passed on to the reconstruction suite. To allow a smooth workflow all processes are automated through the Xplus Handle, which leads to a one button operation principle.
The in-house developed QUICKscan algorithm delivers interpretable results withing a few minutes. For more accurate inspections the scan time can be increased, which results in highest precision.
Putting it in a nutshell CT is a very mighty feature for your inspection. Nevertheless, not every inspection process really needs to use CT. For a detailed consultation feel free to contact us at any time. Our trained experts will suggest you the perfect solution for your inspection problem.
