Geometric Distortion Correction in Computed Radiography
Geometric distortion correction in CR corrects imaging errors due to X-ray divergence and detector curvature. This ensures scale-accurate evaluation of radiographs.
Physical-Chemical Mechanism of Action
CR corrects errors caused by the divergence of the X-ray beam and the curvature of the detector. These deviations can lead to distorted or inaccurate images.
Metallurgical Relevance & Welding Risks
Incorrect CR correction can lead to faulty evaluations of the weld, which poses risks to the quality and safety of the component. Uncorrected errors can lead to mistakes in detecting cracks or irregularities.
Workshop Practice & Instructions
To ensure correct CR correction, the X-ray beam and detector must be precisely calibrated. The specific values vary depending on the equipment and application, but it is important that divergence and curvature are set correctly. If needed, calibrations should be performed by the manufacturer or a qualified technician.
