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…
X-ray dark-field via spectral propagation-based imaging
Jannis N. Ahlers, Konstantin M. Pavlov, Marcus J. Kitchen +1
Dark-field X-ray imaging is a novel modality which visualises scattering from unresolved microstructure. Most dark-field imaging techniques rely on crystals or structured illuminat…
Three-dimensional contrast transfer function in phase-contrast tomography
Darren A. Thompson, Yakov I. Nesterets, Konstantin M. Pavlov +1
A new method is developed for three-dimensional (3D) reconstruction of multi-material objects using propagation-based X-ray phase-contrast tomography (PB-CT) with phase retrieval v…
Tomographic phase and attenuation extraction for a sample composed of unknown materials using X-ray propagation-based phase-contrast imaging
Samantha J. Alloo, David M. Paganin, Kaye S. Morgan +9
Propagation-based phase-contrast X-ray imaging (PB-PCXI) generates image contrast by utilizing sample-imposed phase-shifts. This has proven useful when imaging weakly-attenuating s…
Directional dark-field implicit x-ray speckle tracking using an anisotropic-diffusion Fokker-Planck equation
Konstantin M. Pavlov, David M. Paganin, Kaye S. Morgan +5
When a macroscopic-sized non-crystalline sample is illuminated using coherent x-ray radiation, a bifurcation of photon energy flow may occur. The coarse-grained complex refractive…
Tomographic Reconstruction using Tilted Laue Analyser Based X-ray Phase-Contrast Imaging
M. C. Chalmers, M. J. Kitchen, K. Uesugi +3
Analyser-Based Phase-Contrast imaging (ABPCI) is a phase-contrast imaging method that produces high contrast images of weakly absorbing materials. However, it is only sensitive to…
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…
Single-shot x-ray speckle-based imaging of a single-material object
Konstantin M. Pavlov, Heyang, Li +4
We develop a means for speckle-based phase imaging of the projected thickness of a single-material object, under the assumption of illumination by spatially random time-independent…
Fast three-dimensional phase retrieval in propagation-based x-ray tomography
Darren Thompson, Yakov I. Nesterets, Konstantin M. Pavlov +1
The following paper describes a method for three-dimensional (3D) reconstruction of multi-material objects based on propagation-based X-ray phase-contrast tomography (PB-CT) with p…
CT dose reduction factors in the thousands using X-ray phase contrast
Marcus J. Kitchen, Genevieve A. Buckley, Timur E. Gureyev +6
Phase-contrast X-ray imaging can improve the visibility of weakly absorbing objects (e.g. soft tissues) by an order of magnitude or more compared to conventional radiographs. Previ…
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…
Evaluating the Performance of BSBL Methodology for EEG Source Localization On a Realistic Head Model
Sajib Saha, Rajib Rana, Ya. I. Nesterets +3
Source localization in EEG represents a high dimensional inverse problem, which is severely ill-posed by nature. Fortunately, sparsity constraints have come into rescue as it helps…
Evaluation of Spatial Resolution and Noise Sensitivity of sLORETA Method for EEG Source Localization Using Low-Density Headsets
Sajib Saha, Yakov I. Nesterets, Murat Tahtali +1
Electroencephalography (EEG) has enjoyed considerable attention over the past century and has been applied for diagnosis of epilepsy, stroke, traumatic brain injury and other disor…
