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…

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…
