Low-dose, high-resolution CT of infant-sized lungs via propagation-based phase contrast
James A. Pollock, Kaye Morgan, Linda C. P. Croton +7
Many lung diseases require detailed visualisation for accurate diagnosis and treatment. High-resolution computed tomography (CT) is the gold-standard technique for non-invasive lun…
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 (…
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…
Towards order of magnitude X-ray dose reduction in breast cancer imaging using phase contrast and deep denoising
Ashkan Pakzad, Robert Turnbull, Simon J. Mutch +14
Breast cancer is the most frequently diagnosed human cancer in the United States at present. Early detection is crucial for its successful treatment. X-ray mammography and digital…
Comparison of three reconstruction algorithms for low-dose phase-contrast computed tomography of the breast with synchrotron radiation
Sandro Donato, Simone Caputo, Luca Brombal +17
Three different computed tomography (CT) reconstruction algorithms: Filtered Back Projection (FBP), Unified Tomographic Reconstruction (UTR) and customized Simultaneous Algebraic R…
