Journal ArticleDOI
X-ray Phase Contrast Imaging from Synchrotron to Conventional Sources: A Review of the Existing Techniques for Biological Applications
TL;DR: In this article , the authors present a comprehensive review of phase contrast and dark-field imaging on low-cost X-ray sources, including analyzer-based, grating interferometry and non-interferometric methods such as coded aperture and modulation.
Journal ArticleDOI
Comparison of X-ray speckle-based imaging deflection retrieval algorithms for the optimization of radiation dose.
Hélène Rougé-Labriet,Laurène Quénot,Sylvain Bohic,Barbara Fayard,David M. Paganin,Emmanuel Brun,Sebastien Berujon +6 more
TL;DR: The results obtained using a synchrotron beam suggest that the technique based on optical flow conservation achieves the most accurate retrieval from the lowest number of sample exposures, which constitutes an important step toward the possibility of transferring SBI into the clinic.
Journal ArticleDOI
Directional dark-field implicit x-ray speckle tracking using an anisotropic-diffusion Fokker-Planck equation
Konstantin Mikhailovitch Pavlov,David M. Paganin,Kaye S. Morgan,Heyang Li,Sebastien Berujon,Laurène Quénot,Emmanuel Brun +6 more
TL;DR: In this article, the authors used an anisotropic-diffusion Fokker-Planck approach to model the bifurcated x-ray energy flow and showed how all three components (attenuation, refraction, and locally elliptical diffuse scatter) may be recovered.
Journal ArticleDOI
Implicit tracking approach for X-ray phase-contrast imaging with a random mask and a conventional system
TL;DR: In this paper, a low-coherence system with a conventional X-ray tube and a detector compatible with a clinical routine was proposed for low-dose and patient tomography.
Journal ArticleDOI
Evaluation of simulators for x-ray speckle-based phase contrast imaging.
TL;DR: In this paper, Monte-Carlo, analytical ray-tracing and wave-optics Fresnel propagation were compared to both synchrotron and conventional imaging experiments to obtain their validation.
