An evaluation framework for sparse 4D (3D + time) imaging reconstruction via bootstrapped cross-validation
Yuhe Zhang, Zisheng Yao, Zhe Hu +2
Four-dimensional (4D; 3D + time) microscopic imaging has emerged as a powerful technique for investigating dynamic phenomena in complex systems, enabling direct visualization of st…
4D reconstruction of alumina laser melt pools at 25 kHz via operando X-ray multi-projection imaging
Lars Witte, Eliot Jermann, Zhe Hu +9
Advancing additive manufacturing, e.g., laser powder-bed fusion (LPBF), requires resolving rapid processes such as melt-pool dynamics and keyhole evolution in 4D (3D + time). Opera…
4D Synchrotron X-Ray Multi Projection Imaging (XMPI) for studying multiphase flow dynamics and flow instabilities in porous networks
Patrick Wegele, Zisheng Yao, Jonas Tejbo +11
Flow instabilities such as Haines jumps in porous media are common phenomena that occur on sub-second timescales. X-rays are particularly suitable for investigating these processes…
Constraint-Free Coherent Diffraction Imaging via Physics-Guided Neural Fields
Zhe Hu, Zisheng Yao, Yuhe Zhang +1
CDI is a lensless imaging technique that enables atomic-resolution imaging of non-crystalline specimens and their dynamics. However, its broader implementation has been hindered by…
Time-resolved 3D imaging opportunities with XMPI at ForMAX
Julia Katharina Rogalinski, Zisheng Yao, Yuhe Zhang +11
X-rays are commonly used in imaging experiments due to their penetration power, which enables non-destructive resolution of internal structures in samples that are opaque to visibl…
Super time-resolved tomography
Zhe Hu, Kalle Josefsson, Zisheng Yao +4
Understanding 3D fundamental processes is crucial for academic and industrial applications. Nowadays, X-ray time-resolved tomography, or tomoscopy, is a leading technique for in-si…
Physics-informed 4D X-ray image reconstruction from ultra-sparse spatiotemporal data
Zisheng Yao, Yuhe Zhang, Zhe Hu +3
The unprecedented X-ray flux density provided by modern X-ray sources offers new spatiotemporal possibilities for X-ray imaging of fast dynamic processes. Approaches to exploit suc…
Development of crystal optics for Multi-Projection X-ray Imaging for synchrotron and XFEL sources
Valerio Bellucci, Sarlota Birnsteinova, Tokushi Sato +27
X-ray Multi-Projection Imaging (XMPI) is an emerging technology that allows for the acquisition of millions of 3D images per second in samples opaque to visible light. This breakth…
4D-ONIX: A deep learning approach for reconstructing 3D movies from sparse X-ray projections
Yuhe Zhang, Zisheng Yao, Robert Klöfkorn +2
The X-ray flux provided by X-ray free-electron lasers and storage rings offers new spatiotemporal possibilities to study in-situ and operando dynamics, even using single pulses of…
Development towards high-resolution kHz-speed rotation-free volumetric imaging
Eleni Myrto Asimakopoulou, Valerio Bellucci, Sarlota Birnsteinova +19
X-ray multi-projection imaging (XMPI) provides rotation-free 3D movies of optically opaque samples. The absence of rotation enables superior imaging speed and preserves fragile sam…
