Abstract
The present paper discusses the adaptation of a digital radiographic scintillator-based linear detector array (LDA) in a third-generation continuous-rotate X-ray industrial tomographic imaging system. The LDA has been used in a collinear configuration. Behaviour of the reconstructed parameter, i.e., approximate linear absorption coefficient at the ‘effective energy’ with varying anode voltage of the constant potential X-ray tube is studied. Experiments have been carried out with a solid cylindrical Perspex block (50 mm dia.) in 50–150 kV tube voltage range. The experimentally reconstructed attenuation values were used to predict the effective energy of the X-ray beam. The present study also includes a discussion on the statistical behaviour of the reconstructed linear attenuation values.
