Development and Validation of Patient-Specific Monte Carlo Dosimetry for Synchrotron Breast Phase-Contrast CT
Amir Entezam, Ashkan Pakzad, Christopher J. Hall +11
This study develops and validates a patient-specific Monte Carlo (MC) dosimetry framework for propagation-based phase-contrast breast CT (BCT) at the Imaging and Medical Beamline (…
Efficiency limits in in-line imaging
Timur E. Gureyev, David M. Paganin, Harry M. Quiney
In-line phase-contrast imaging, also known as propagation-based imaging or Gabor holography, is capable of delivering significant gains in image quality, compared to attenuation-ba…
Quantum Jacobi-Davidson Method
Shaobo Zhang, Akib Karim, Harry M. Quiney +1
Computing electronic structures of quantum systems is a key task underpinning many applications in photonics, solid-state physics, and quantum technologies. This task is typically…
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…
Moments-based quantum computation of the electric dipole moment of molecular systems
Michael A. Jones, Harish J. Vallury, Manolo C. Per +2
With rapid progress being made in the development of platforms for quantum computation, there has been considerable interest in whether present-day and near-term devices can be use…
