CORE-Deblur: Parallel MRI Reconstruction by Deblurring Using Compressed Sensing
Efrat Shimron, Andrew G. Webb, Haim Azhari
In this work we introduce a new method that combines Parallel MRI and Compressed Sensing (CS) for accelerated image reconstruction from subsampled k-space data. The method first co…
Gradient Coil Design and Realization for a Halbach-Based MRI System
Bart de Vos, Patrick Fuchs, Thomas O'Reilly +2
In this paper we design and construct gradient coils for a Halbach permanent magnet array magnetic resonance (MR) scanner. The target field method, which is widely applied for the…
Combining Deep Learning and 3D Contrast Source Inversion in MR-based Electrical Properties Tomography
Reijer L. Leijsen, Cornelis A. T. van den Berg, Andrew G. Webb +2
Magnetic resonance-electrical properties tomography (MR-EPT) is a technique used to estimate the conductivity and permittivity of tissues from MR measurements of the transmit magne…
High-Permittivity Pad Design Tool for 7T Neuroimaging and 3T Body Imaging
J. H. F. van Gemert, W. M. Brink, A. G. Webb +1
Purpose: High-permittivity materials in the form of flexible 'dielectric pads' have proved very useful for addressing RF inhomogeneities in high field MRI. Finding the optimal desi…
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…
Flexible and compact hybrid metasurfaces for enhanced ultra high field in vivo magnetic resonance imaging
Rita Schmidt, Alexey Slobozhanyuk, Pavel Belov +1
Developments in metamaterials and related structures such as metasurfaces have opened up new possibilities in designing materials and devices with unique properties. The main progr…
