Accelerated MP2RAGE imaging using Cartesian phyllotaxis readout and compressed sensing reconstruction

Jean-Philippe Thiran, Tobias Kober, Tom Hilbert, Reto Meuli

Purpose MP2RAGE T-1-weighted imaging has been shown to be beneficial for various applications, mainly because of its good grey-white matter contrast, its B-1-robustness and ability to derive T(1)maps. Even using parallel imaging, the method requires long a ...

Compressed sensing with signal averaging for improved sensitivity and motion artifact reduction in fluorine-19 MRI

Tobias Kober, Tom Hilbert, Jérôme Yerly, Ruud van Heeswijk, Elena Najdenovska

Fluorine-19 (F-19) MRI of injected perfluorocarbon emulsions (PFCs) allows for the non-invasive quantification of inflammation and cell tracking, but suffers from a low signal-to-noise ratio and extended scan time. To address this limitation, we tested the ...

Implementation of Functional Microfluidic Dispensing Tools Enabling Enhanced Control in Extrusion Bioprinting

Ludovic Serex

Inspired from additive manufacturing's success, the structuring of biocompatible materials through bioprinting has become a growing field of research in the past fifteen years. It opened the door to a plethora of applications ranging from the fabrication o ...

Angular Color Prediction Model for Anisotropic Halftone Prints on a Metallic Substrate

Roger Hersch, Lin Yang, Petar Pjanic

Under specular reflection, non-isotropic halftones such as line halftones printed on an ink-receiving plastic layer superposed with a metallic layer change their colors upon in-plane rotation of the print. This color change is due to the orientation-depend ...

Rapid inkjet printing of high catalytic activity Co3O4 /N-rGO layers for oxygen reduction reaction

Hubert Girault, Victor Costa Bassetto, Emad Oveisi, Andreas Stephan Lesch, Véronique Amstutz

The accurate and reproducible large-scale production of catalyst layers containing low-cost, abundant electrocatalysts gains in importance. Herein, pivotal factors are discussed that need to be considered when a combined inkjet printing and photonic curing ...

Printing materials and technologies in the 15th−17th century book production: an undervalued research field

Giovanni Colavizza, Fauzia Albertin

We present a systematic non-invasive investigation of a large corpus of early printed books, exploiting multiple techniques. This work is part of a broader project -- Argeia -- aiming to study early printing technologies, their evolution and, potentially, ...

Unified rule based correction for corners in proximity lithography mask using high resolution features

Hans Peter Herzig, Toralf Scharf, Krishnaparvathy Puthankovilakam

Printing industry and printing techniques are increasing its market value by new methodologies. The resolution and accuracy of the pattern transfer is always a challenge for the industry, especially for the proximity printing industries which use mask alig ...

Image reproduction with compensation of luminance adaptation

Mahmut Sami Arpa

We introduce an image reproduction model that retargets colors for printing purposes to ensure similar luminance perception under photopic and scotopic vision. Our model is based on the physiological functioning of the rod and cone cells in the retina in v ...

Color changing effects with cross-halftone prints

Roger Hersch, Petar Pjanic

We propose new methods for creating color varying prints with classical cyan, magenta, yellow inks on a metallic specularly reflecting or on a white diffusely reflecting substrate. We use a special cross-line halftone with optimized surface coverages of th ...

Color Changing Prints on a Metallic Substrate

Petar Pjanic

Printing on a flat metallic substrate has gained popularity in recent years. The reflection of light on a specularly reflecting metallic substrate differs strongly from the reflection of light on a diffusely reflecting medium such as paper. Direct prints o ...
