Generalized Zernike Phase-Contrast Imaging
Christian Dwyer, David M. Paganin
Zernike phase-contrast imaging is unique among imaging techniques in that it enables the upper limit of Fisher information allowed by quantum mechanics. Here we show that, in a dep…
On optimization of Paganin's method for propagation-based X-ray phase-contrast imaging and tomography
Timur E. Gureyev, David M. Paganin, Ashkan Pakzad +1
Paganin's method for image reconstruction in propagation-based phase-contrast X-ray imaging and tomography has enjoyed broad acceptance in recent years, with over one thousand publ…
Active wave-particle clusters
Rahil N. Valani, David M. Paganin
Active particles are non-equilibrium entities that uptake energy and convert it into self-propulsion. A dynamically rich class of inertial active particles having features of wave-…
Quantitative Stain Mapping in X-ray Virtual Histology
Dominik John, David M. Paganin, Marie-Christine Zdora +14
Virtual histology is an emerging field in biomedicine that enables three-dimensional tissue visualization using X-ray micro-computed tomography. However, the method still lacks the…
Demonstrating a family of X-ray dark-field retrieval approaches on a common set of samples
Samantha J. Alloo, Ying Ying How, Jannis N. Ahlers +3
Sensitive to scattering from unresolved sample structures, the dark-field channel in full-field X-ray imaging provides complementary information to that offered by conventional att…
Ghost projection via focal-field diffraction catastrophes
James A. Monro, Andrew M. Kingston, David M. Paganin
Ghost projection is the reversed process of computational classical ghost imaging that allows any desired image to be synthesized using a linear combination of illuminating pattern…
