The development of MRI systems operating at or above 7 T has provided researchers with a
new window into the human body, yielding improved imaging speed, resolution and signal …

Magnetic resonance imaging (MRI) has become an unrivalled medical diagnostic technique
able to map tissue anatomy and physiology non-invasively. MRI measurements are …

Purpose A calibration‐free parallel transmission method is investigated to mitigate the
radiofrequency (RF) field inhomogeneity problem in brain imaging at 7 Tesla (T). Theory and …

At ultra-high magnetic fields, such as 7T, MR imaging can noninvasively visualize the brain
in unprecedented detail and through enhanced contrast mechanisms. The increased SNR …

With Transmit SENSE, we demonstrate the feasibility of uniformly exciting a volume such as
the human brain at 7T through the use of an original minimalist transmit k‐space coverage …

This paper reviews the field of multiple or parallel radiofrequency (RF) transmission for
magnetic resonance imaging (MRI). Currently the use of ultra-high field (UHF) MRI at 7 tesla …

Abstract Functional MRI (fMRI) at 7 T and above provides improved Signal-to-Noise Ratio
and Contrast-to-Noise Ratio compared to 3 T acquisitions. In addition to the beneficial …

Spatially tailored radio frequency (RF) excitations accelerated with parallel transmit systems
provide the opportunity to create shaped volume excitations or mitigate inhomogeneous B1 …

Arrays of radiofrequency coils are widely used in magnetic resonance imaging to achieve
high signal-to-noise ratios and flexible volume coverage, to accelerate scans using parallel …
