Abstract

Computed X-ray tomography (CT) is now a well established method used to reconstruct the inner structures of components. It has the advantage over conventional X-ray radiographs of easier interpretation of images, since the component under inspection can be “sliced” and observed to any depth. With simple X-ray images, all the inner structure information is compressed. In CT imagery a set of X ray radiographs is recorded along different projections around the component and a special algorithm is then used to reconstruct the unique distribution of attenuation coefficients inside the component (Kassab and Hsieh 1987; Jacoby and Lingenfelter 1989; Garvie and Sorell 1990). This map of attenuation coefficients corresponds to the inner structure of the part expressed as the ability of the matter to attenuate the rays.
