This presentation will describe novel results of research at Oak Ridge National Laboratory, using new commercially available non-destructive x-ray techniques to make engineering measurements on diesel particulate filters.  We will present data showing the ability to visualize and measure flaws in substrates, quantify the distribution of individual or multiple wash-coats, and make through-the-can evaluations of the distribution of soot, ash, and thermal regeneration damage.
