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…
