Industrial Computed Tomography Beam Hardening Correction
Industrial computed tomography beam hardening correction eliminates artifacts in CT images caused by absorption of low-energy photons, ensuring measurement accuracy.
Physical-Chemical Mechanism of Action
Computed tomography (CT) uses X-rays that are absorbed differently by different materials. Low-energy photons are absorbed more than higher-energy photons, causing artifacts in the image. Beam hardening correction corrects these effects using mathematical algorithms.
Metallurgical Relevance & Welding Risks
In the workshop, incorrectly corrected CT images can lead to misinformation, making the material assessment wrong. This can result in inaccurate welding parameters and potential defects in components. It is therefore crucial that the correction is done accurately and precisely.
Workshop Practice & Instructions
To minimize artifacts and ensure measurement accuracy:
1. Use high-energy X-rays for CT scanning.
2. Apply beam hardening correction with specialized software algorithms.
3. Regularly check CT images for artifacts and correct them if necessary.
