On imaging capabilities of the Imaging and Medical beamline at the Australian Synchrotron
T. E. Gureyev, K. M. Pavlov, C. J. Hall +6
Several propagation-based and analyser-based X-ray phase-contrast imaging experiments with over 100 m between the imaged objects and the detector were carried out at the Imaging an…
Fast Patient-Specific Breast CT Dosimetry: 22-Fold Acceleration of Monte Carlo MGD Estimation
Amir Entezam, Ashkan Pakzad, Christopher J. Hall +9
Accurate patient-specific mean glandular dose (MGD) estimation in breast computed tomography (BCT) requires anatomically realistic models, but high-resolution patient-derived phant…
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 (…
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…
