Journal ArticleDOI
Emphysema diagnosis using X-ray dark-field imaging at a laser-driven compact synchrotron light source
Simone Schleede,Felix G. Meinel,Martin Bech,Martin Bech,Julia Herzen,Klaus Achterhold,Guillaume Potdevin,Andreas Malecki,Silvia Adam-Neumair,Sven F. Thieme,Fabian Bamberg,Konstantin Nikolaou,Alexander Bohla,Ali Oe. Yildirim,Roderick J. Loewen,Martin Gifford,Ronald D. Ruth,Oliver Eickelberg,Maximilian F. Reiser,Franz Pfeiffer +19 more
TL;DR: In this paper, the authors used grating-based dark-field images of emphysematous vs. healthy lung tissue to monitor the morphological changes that the alveoli network undergoes in the progression of these diseases, which is related to small-angle scattering in the sample.
Journal ArticleDOI
Diagnosing and Mapping Pulmonary Emphysema on X-Ray Projection Images: Incremental Value of Grating-Based X-Ray Dark-Field Imaging
Felix G. Meinel,Felix Schwab,Simone Schleede,Martin Bech,Martin Bech,Julia Herzen,Julia Herzen,Klaus Achterhold,Sigrid Auweter,Fabian Bamberg,Ali Oe. Yildirim,Alexander Bohla,Oliver Eickelberg,Rod Loewen,Martin Gifford,Ronald D. Ruth,Maximilian F. Reiser,Franz Pfeiffer,Konstantin Nikolaou +18 more
TL;DR: In a murine model, the complementary information provided by X-ray transmission and dark-field images adds incremental diagnostic value in detecting pulmonary emphysema and visualizing its regional distribution as compared to conventionalX-ray projections.
Journal ArticleDOI
Multimodal hard X-ray imaging of a mammography phantom at a compact synchrotron light source.
Simone Schleede,Martin Bech,Martin Bech,Klaus Achterhold,Guillaume Potdevin,Martin Gifford,Rod Loewen,Cecile Limborg,Ronald D. Ruth,Franz Pfeiffer +9 more
TL;DR: Dose-compatible measurements of a mammography phantom clearly demonstrate an increase in contrast attainable through differential phase and dark-field imaging over conventional attenuation-based projections.
Journal ArticleDOI
An algebraic iterative reconstruction technique for differential X-ray phase-contrast computed tomography.
Jian Fu,Simone Schleede,Renbo Tan,Liyuan Chen,Martin Bech,Martin Bech,Klaus Achterhold,Martin Gifford,Rod Loewen,Ronald D. Ruth,Franz Pfeiffer +10 more
TL;DR: This work comprises a numerical study of the algorithm and its experimental verification using a dataset measured at a two-grating interferometer setup, and expects a significant impact of the method for improving future medical and industrial DPC-CT applications.
Journal ArticleDOI
Comparison of contrast-to-noise ratios of transmission and dark-field signal in grating-based X-ray imaging for healthy murine lung tissue
Felix Schwab,Simone Schleede,Dieter Hahn,Martin Bech,Martin Bech,Julia Herzen,Julia Herzen,Sigrid Auweter,Fabian Bamberg,Klaus Achterhold,Ali Oe. Yildirim,Alexander Bohla,Oliver Eickelberg,Rod Loewen,Martin Gifford,Ronald D. Ruth,Maximilian F. Reiser,Konstantin Nikolaou,Franz Pfeiffer,Felix G. Meinel +19 more
TL;DR: The contrast-to-noise ratio of dark-field images compares more favorably to the contrast- to-no noise ratio of transmission images for peripheral lung regions as compared to central regions.
