Refraction beats attenuation in breast CT
Michał Rawlik, Alexandre Pereira, Simon Spindler +17
For a century, clinical X-ray imaging has visualised only the attenuation properties of tissue, which fundamentally limits the contrast, particularly in soft tissues like the breas…
High aspect ratio arrays of Si nano-pillars using displacement Talbot lithography and gas-MacEtch
Z. Shi, K. Jefimovs, M. Stampanoni +1
Structuring Si in arrays of vertical high aspect ratio pillars, ranging from nanoscale to macroscale feature dimensions, is essential for producing functional interfaces for many a…
Photon-counting spectral phase-contrast mammography
E. Fredenberg, E. Roessl, T. Koehler +10
Phase-contrast imaging is an emerging technology that may increase the signal-difference-to-noise ratio in medical imaging. One of the most promising phase-contrast techniques is T…
High aspect ratio silicon structures by Displacement Talbot lithography and Bosch etching
Konstantins Jefimovs, Lucia Romano, Joan Vila-Comamala +6
Despite the fact that the resolution of conventional contact/proximity lithography can reach feature sizes down to ~0.5-0.6 micrometers, the accurate control of the linewidth and u…
Hot embossing of Au- and Pb- based alloys for X ray grating fabrication
Lucia Romano, Joan Vila-Comamala, Helmut Schift +1
Grating-based X-ray phase-contrast interferometry has a high application impact in material science and medicine for imaging of weakly absorbing (low Z) materials and soft tissues.…
Towards Sub-micrometer High Aspect Ratio X-ray Gratings by Atomic Layer Deposition of Iridium
Joan Vila-Comamala, Lucia Romano, Vitaliy Guzenko +3
X-ray grating interferometry is an excellent technique for X-ray phase contrast imaging and X-ray wavefront sensing with applications in materials science, biology and medical diag…
