SEM-EDX validation of DECT on the surface of the sample, despite imaging differences making the overlay imperfect. (a) segmented high attenuation voxels in the DECT image, (b) segmented bromide mapping from SEM-EDX, (c) overlay of the SEM-EDX elemental mapping and the DECT image after automated registration. The blue phase indicates exact overlay of the two images: about 1/3 of the SEM-EDX segmented pixels.
