Claim:
1. A method for elementally detecting variations in density within a component, the method comprising: providing a computed tomography device, comprising: positioning the component between the radiation source and the detector; rotating the component orthogonally to the at least one grating; directing radiation from the radiation source to the detector to acquire information from the component; generating at least one phase contrast image and at least one dark field contrast image of the component corresponding to variations in density with the information from the component; incrementally rotating one or both of the component and the computed tomography device; correlating the variations in density to a foreign mass; and displaying foreign mass distribution within the component; wherein the rotating of the component orthogonally provides information relating to plies of the component other than 90 degree plies of the component and the incrementally rotating provides 360 degree views of the component.
