Direct volumetric reconstruction for highly compressive x-ray fluorescence ghost tomography
A. Ben-Yehuda, A. Rack, S. Shwartz +1
X-ray fluorescence (XRF) enables element-specific, nondestructive imaging, but conventional raster scanning scales poorly with sample size, particularly for tomography, because mea…

Phase-Sensitive Nonlinear X-Ray Response in a Charge-Density-Wave Quantum Material
S. Sofer, G. J. Man, A. Bombardi +1
We report a phase-sensitive nonlinear x-ray response in the charge-density-wave material 1T-TaS2, revealed through x-ray parametric down-conversion into the ultraviolet. Extending…

Human-organ-scale x-ray fluorescence ghost imaging for radioisotope-free diagnostics
E. Levinson, R. H. Shukrun, N. Vigano +1
A wide range of diagnostic information in medicine is currently obtained using radioactive tracers. While central to nuclear medicine, these methods are inherently constrained: rad…
