摘要

This issue of Insight has something of interest for all readers as the papers show that the weaknesses of current NDT can be reduced for bridge decks, eddy current instrumentation, real-time image processing in industrial CT X-ray systems and in quality control. W De Corte's paper shows that, by determining the pressure footprint of truck tyres on steel bridge decks, the failure analysis of these structures is now better understood. Spurious experimental results are the bane of an NDT inspector's work as he attempts to detect defects. These are prevalent in industrial X-ray CT systems with limited radiation energy. Wei Yu et al have developed new algorithms to reduce the number of such artefacts.
