Simulation of beam hardening in X-ray tomography and its correction using linearisation and pre-filtering approaches

Autor: T. Jayakumar, K. Arunmuthu, M Ashish, T. Saravanan, John Philip, B. P. C. Rao

Publikováno v: Insight - Non-Destructive Testing and Condition Monitoring. 55:540-547

If a monoenergetic X-ray beam is passed through the object, then the attenuation coefficient at any particular point inside the object is a constant. When a polyenergetic X-ray beam, consisting of photons of different energies, passes through the mat

Image processing of radiographs of tube-to-tubesheet weld joints for enhanced detectability of defects

Autor: P. Arun Kumar, Baldev Raj, T. Jayakumar, T. Saravanan, John Philip, K. Arunmuthu

Publikováno v: Insight - Non-Destructive Testing and Condition Monitoring. 50:298-303

This paper discusses the application of digital image processing, particularly Fourier space filters over the spatial filters, for enhanced detectability of defect features in the tube-to-tubesheet weld samples. The Butterworth band-pass filter is fo
