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 …

Parallel transmission is a very promising candidate technology to mitigate the inevitable
radio-frequency (RF) field inhomogeneity in magnetic resonance imaging at ultra-high field …

The 9.4 T scanner in Maastricht is a whole-body magnet with head gradients and parallel RF
transmit capability. At the time of the design, it was conceptualized to be one of the best fMRI …

Functional mapping of cerebral blood volume (CBV) changes has the potential to reveal
brain activity with high localization specificity at the level of cortical layers and columns. Non …

Current spokes pulse design methods can be grouped into methods based either on sparse
approximation or on iterative local (gradient descent‐based) optimization of the transverse …

The use of increasingly strong magnetic fields in magnetic resonance imaging (MRI)
improves sensitivity, susceptibility contrast, and spatial or spectral resolution for functional …

Purpose Some advanced RF pulses, like multidimensional RF pulses, are often long and
require substantial computation time because of a number of constraints and requirements …

Designing multidimensional radiofrequency pulses for clinical application must take into
account the local specific absorption rate (SAR) as controlling the global SAR does not …

We consider an excitation pulse with piecewise constant gradient trajectories and radio
frequency (RF) waveforms such that the solution of the Bloch equations without relaxation …

Purpose In order to benefit from the increased spectral bandwidth at ultrahigh field (UHF),
the use of parallel transmission (pTx) to mitigate flip‐angle inhomogeneity in chemical …
