Flexible metasurface for improving brain imaging at 7T
Vladislav Koloskov, Wyger Brink, Andrew Webb +1
Ultra-high field MRI offers unprecedented detail for non-invasive visualization of the human brain. However, brain imaging is challenging at 7T due to the B field inhomogenei…
Application of topological edge states in magnetic resonance imaging
Viktor M. Puchnin, Olga V. Matvievskaya, Alexey P. Slobozhanyuk +2
Topological edge states in electromagnetic systems feature a set of attracting fundamental properties and unveil prospective applications based on disorder robustness and tailored…
Improving B1 homogeneity in abdominal imaging at 3 T with light and compact metasurface
Vsevolod Vorobyev, Alena Shchelokova, Alexander Efimtcev +5
Radiofrequency field inhomogeneity is a significant issue in imaging large fields of view in high- and ultrahigh-field MRI. Passive shimming with coupled coils or dielectric pads i…
Locally Enhanced Image Quality with Tunable Hybrid Metasurfaces
Alena V. Shchelokova, Alexey P. Slobozhanyuk, Irina V. Melchakova +4
Metasurfaces represent a new paradigm in artificial subwavelength structures due to their potential to overcome many challenges typically associated with bulk metamaterials. The ab…
Near-field imaging of spin-locked edge states in all-dielectric topological metasurfaces
A. Slobozhanyuk, A. V. Shchelokova, X. Ni +6
A new class of phenomena stemming from topological states of quantum matter has recently found a variety of analogies in classical systems. Spin-locking and one-way propagation hav…
