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…
A Parametric Study of Radiative Dipole Body Array Coil for 7 Tesla MRI
Anna A. Hurshkainen, Bart Steensma, Stanislav B. Glybovski +5
In this contribution we present numerical and experimental results of a parametric quantitative study of radiative dipole antennas in a phased array configuration for efficient bod…
A Novel Metamaterial-Inspired RF-coil for Preclinical Dual-Nuclei MRI
A. Hurshkainen, A. Nikulin, E. Georget +9
In this paper we propose, design and test a new dual-nuclei RF-coil inspired by wire metamaterial structures. The coil operates due to resonant excitation of hybridized eigenmodes…
Element Decoupling of 7T Dipole Body Arrays by EBG Metasurface Structures: Experimental Verification
Anna A. Hurshkainen, Tatyana A. Derzhavskaya, Stanislav B. Glybovski +4
Metasurfaces are artificial electromagnetic boundaries or interfaces usually implemented as two-dimensional periodic structures with subwavelength periodicity and engineered proper…
