Claim One:
1. An inspection method, comprising: introducing a mixture of expanding foam and a particulate into a region of interest of an object; fixing the particulate relative to the object in the region of interest; and acquiring image data including the object and particulate using x-ray radiation, wherein a density of the particulate is greater than that of the object to provide contrast between the object and the region of interest in the image data, wherein the object is a fuel injector for a gas turbine engine, wherein the particulate includes a first material and the object includes a second material, the first material having a mass attenuation coefficient that is greater than a mass attenuation coefficient of the second material and wherein the expanding foam includes a third material having a mass attenuation coefficient that is smaller than the mass attenuation coefficient of the second material.
