Duke D phantom composed of PLA plastic and water scanned by the X-ray fan beam coded aperture imaging system. (a) Photograph of Duke D phantom. (b) Transmission scan of Duke D Phantom. (c) Multiplexed XRD data acquired when fan beam was at the location of the red line in (b). (d) XRD image with artificial coloring based on the mean momentum transfer (q) value of each voxel’s XRD spectrum. (e) Combined transmission + momentum transfer (q) colorized (TQC) image of Duke D. (f) Mean XRD spectrum obtained from the marked 3 × 3 voxel regions in (e) (with standard deviation bars), compared against the XRD spectrum of PLA and water measured in a commercial diffractometer.
