Interior X-ray diffraction tomography with low-resolution exterior information
Zheyuan Zhu, Alexander Katsevich, Shuo Pang
X-ray diffraction tomography (XDT) resolves spatially-variant XRD profiles within macroscopic objects, and provides improved material contrast compared to the conventional transmis…
