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…
