Full-field fluorescence computed tomography (F3CT) using a calibrated virtual cone-beam pinhole geometry
Thomas Zillhardt, Yunhui Chen, Alexander Rack +4
We present F3CT, a synchrotron-based hyperspectral full-field fluorescence computed tomography technique that avoids raster scanning by combining a pinhole aperture with an energy-…
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…
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…
Advanced structural characterization of single-walled carbon nanotubes with 4D-STEM
Antonin Louiset, Daniel Förster, Vincent Jourdain +5
Single wall carbon nanotubes (SWCNT) exhibit remarkable optical and electrical properties making them one of the most promising materials for next generation electronic and optoele…
Noise2Ghost: Self-supervised deep convolutional reconstruction for ghost imaging
Mathieu Manni, Dmitry Karpov, K. Joost Batenburg +2
We present a new self-supervised deep-learning-based Ghost Imaging (GI) reconstruction method, which provides unparalleled reconstruction quality for noisy acquisitions among unsup…
