Are Pedelec crashes different to bicycle crashes?: A comparison of national accident data in Germany

Autor: Mönnich, Jörg, Lich, Thomas, Maier, Oliver

Since 2014, a distinction between Pedelec (electrical support up to 25 km/h) and bicycle crashes is made in official police reported accidents with personal injuries in Germany. Yet, no comparative analysis using national data is available, moreover

Fork bending self-oscillation on bicycles influencing braking performance

Autor: Skatulla, Johann, Maier, Oliver, Schmidt, Stephan

This work deals with a fork bending oscillation phenomenon observed during hard braking on bicycles. The observed oscillation is described with experimental data and an attempt is made to understand the underlying root cause. Therefore, a multibody m

Joint multi-field T$_1$ quantification for fast field-cycling MRI

Autor: Bödenler, Markus, Maier, Oliver, Stollberger, Rudolf, Broche, Lionel M., Ross, P. James, MacLeod, Mary-Joan, Scharfetter, Hermann

Purpose: Recent developments in hardware design enable the use of Fast Field-Cycling (FFC) techniques in MRI to exploit the different relaxation rates at very low field strength, achieving novel contrast. The method opens new avenues for in vivo char

Non-linear fitting with joint spatial regularization in Arterial Spin Labeling

Autor: Maier, Oliver, Spann, Stefan M, Pinter, Daniela, Gattringer, Thomas, Hinteregger, Nicole, Thallinger, Gerhard G., Enzinger, Christian, Pfeuffer, Josef, Bredies, Kristian, Stollberger, Rudolf

Multi-Delay single-shot arterial spin labeling (ASL) imaging provides accurate cerebral blood flow (CBF) and, in addition, arterial transit time (ATT) maps but the inherent low SNR can be challenging. Especially standard fitting using non-linear leas

Report

CG-SENSE revisited: Results from the first ISMRM reproducibility challenge

Autor: Maier, Oliver, Baete, Steven H., Fyrdahl, Alexander, Hammernik, Kerstin, Harrevelt, Seb, Kasper, Lars, Karakuzu, Agah, Loecher, Michael, Patzig, Franz, Tian, Ye, Wang, Ke, Gallichan, Daniel, Uecker, Martin, Knoll, Florian

Publikováno v: Magnetic Resonance in Medicine 2021;85:1821-1839

Purpose: The aim of this work is to shed light on the issue of reproducibility in MR image reconstruction in the context of a challenge. Participants had to recreate the results of "Advances in sensitivity encoding with arbitrary k-space trajectories
