Abstract: An inspection method include introducing a mixture of expanding foam and a particulate material into a region of interest of an object, fixing the powder within the region of the interest relative to the object, and acquiring image data of the object and particulate mixture using an x-ray source and an x-ray detector. The particulate has a density that is greater than the density of a material forming the object to provide contrast between the region of interest and the object in an image generated using the image data.
