Images of weakly attenuating materials and nondestructive evaluation usinga tube source of X-rays

Images of weakly attenuating materials were obtained using an image intensi fied based computed tomography scanner and a tube source of X-rays. The ima ge of a plastic material which contains an internal defect is studied thoro ughly at optimum value. A reconstruction programme written in PASCAL gives the reconstruction matrix of the linear attenuation coefficients and simula tes the matrix and the related tomography. The images are analyzed using th e profile data showing the internal defect of the objects in order to obtai n the reliable information at optimum value.
