Computed Tomographic Beam Hardening Correction
Computed tomography beam hardening correction is an algorithm that eliminates artifacts in CT images by accounting for the absorption of low-energy X-rays. This improves the accuracy of density determination in massive components.
Physikalisch-chemischer Wirkmechanismus
The computed tomography beam hardening correction corrects artifacts caused by the different absorption of various energy levels of an X-ray spectrum. Low-energy rays are absorbed more strongly than high-energy ones, leading to density distortions.
Metallurgical Relevance & Welding Risks
In the workshop, this correction method helps make CT images more precise and make flaws or defects more visible. Without proper beam hardening correction, density differences in components cannot be accurately represented, which can lead to misinterpretations.
Werkstattpraxis & Handlungsanweisungen
To effectively use computed tomography beam hardening correction, CT equipment must be properly calibrated and configured. It is important that the operator applies the algorithm correctly and regularly checks image quality. If necessary, special software settings should be made to minimize artifacts.
