Abstract
Real time, high performance and reliable inspections are desired in many fields including weld inspection, food control and medical imaging. To achieve this level of NDE, the most commonly used approach consists of applying several inspection modalities. In the field of weld inspection, ultrasonic testing (UT) is often carried out first, and radiological examination is used next to confirm the detection, identification and characterisation of defects previously revealed with ultrasounds. Sometimes, the same inspection modality is used in different operating conditions to obtain better results. For example, in conventional medical MRI, multi-spectral acquisitions are systematically performed and different images or volumes corresponding to the same organ are taken into account to achieve a more reliable and precise analysis of diseases [1–2]. At the moment, most radiological examinations in weld inspection use film radiography. This technique is slow and often does not allow 100% control. Replacing film radiography by real time X-ray imaging systems appears a reasonable alternative to reduce cost of consumables and increase inspection speed.
