Abstract
Conventional computerized axial tomography images show the spatial variation in the linear attenuation coefficient in a cross-section of a specimen. However, no information is present to enable one to predict the location nor concentration of an atomic element in the image. Differential X-ray absorptiometry is a well established analytic technique for determining the concentration of an atomic element in a specimen. In this thesis, it is shown that by applying differential X-ray absorptiometry to computerized axial tomography, element specific images of a cross-section of a specimen can be produced using either radioisotope or tube sources. Differential X-ray ab...
