Ultra-high-field MRI of the musculoskeletal system at 7.0T
Journal of Magnetic Resonance Imaging, 2007AbstractHigh‐field (3T) and ultra‐high‐field (UHF, 7T and above) systems are increasingly being used to explore potential musculoskeletal applications because they provide a high intrinsic signal‐to‐noise ratio (SNR), potentially higher resolution (spatial and temporal), and improved contrast.

[Survey of risks related to static magnetic fields in ultra high field MRI].
RoFo : Fortschritte auf dem Gebiete der Rontgenstrahlen und der Nuklearmedizin, 2008 In magnetic resonance imaging (MRI), substantial improvements with respect to sensitivity are expected due to the development of so-called ultra high field scanners, i. e., whole-body scanners with a magnetic field strength of 7 T or above. Users of this technology need to evaluate this benefit for potential risks since commercially available systems ...

Hardware Considerations in Ultra High Field MRI
, 2007 Ultra high field MRI systems present a number of unique challenges to the system designer and integrator beyond simply scaling up the performance of a lower field system. The primary areas of concern are the magnet, gradient coils and drivers, and RF coils and coil interface.

Epilepsy under the scope of ultra-high field MRI
Epilepsy & Behavior, 2021Ultra-high field magnetic resonance imaging (UHF-MRI) is capable of unraveling anatomical structures in a submillimeter range. In addition, its high resonance regime allows the quantification of constitutive molecules in a spatially sensitive manner, a crucial capability for determining the extent and localization of a probable epileptogenic region or ...

Ultra High Field MRI: High-Frequency Coils
, 2007 This chapter reviews RF volume, array, and surface coil modeling, design, construction, control, safety, and human in-vivo application examples for field strengths from 4 to 9.4 T. While a comprehensive variety of coils is included, focus is on the transmission line (TEM) technology head, body, surface, and array coils developed by the author over the ...

Macroscopic Susceptibility in Ultra High Field MRI
Journal of Computer Assisted Tomography, 1999Magnetic susceptibility provides the basis for functional studies and image artifacts in MRI. In this work, magnetic susceptibility and the associated artifacts were analyzed at 8 T in phantoms and in the human head.A mineral oil phantom was constructed in which three cylindrical air-filled tubes were inserted.
