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…
Signal-to-noise and spatial resolution in in-line imaging. 3. Optimization using a simple model
T. E. Gureyev, D. M. Paganin, H. M. Quiney
The problem of optimization of propagation-based phase-contrast imaging setups is considered in the case of projection X-ray imaging and three-dimensional tomography with phase ret…
Signal-to-noise and spatial resolution in in-line imaging. 2. Phase-contrast tomography
T. E. Gureyev, D. M. Paganin, K. M. Pavlov +2
In the first part of this paper, quantitative aspects of propagation-based phase-contrast imaging (PBI) were investigated using theoretical and numerical approaches, as well as exp…
High-energy X-ray phase-contrast CT of an adult human chest phantom
Jannis N. Ahlers, Lorenzo D'Amico, Henriette Bast +15
Propagation-based phase-contrast X-ray imaging is a promising technique for in~vivo medical imaging, offering lower radiation doses than traditional attenuation-based imaging. Prev…
Signal-to-noise and spatial resolution in in-line imaging. 1. Basic theory, numerical simulations and planar experimental images
T. E. Gureyev, D. M. Paganin, H. M. Quiney
Signal-to-noise ratio and spatial resolution are quantitatively analysed in the context of in-line (propagation based) X-ray phase-contrast imaging. It is known that free-space pro…
Dark-field signal extraction in propagation-based phase-contrast imaging
T. E. Gureyev, D. M. Paganin, B. Arhatari +4
A method for extracting the dark-field signal in propagation-based phase-contrast imaging is proposed. In the case of objects consisting predominantly of a single material, or seve…
Monomorphous decomposition method for phase retrieval and phase-contrast tomography
T. E. Gureyev, Ya. I. Nesterets
We show that an arbitrary spatial distribution of complex refractive index inside an object can be exactly represented as a sum of two "monomorphous" complex distributions, i.e. th…
