The introduction of compressed sensing for increasing imaging speed in magnetic
resonance imaging (MRI) has raised significant interest among researchers and clinicians …

Purpose Fast MRI acquisitions often rely on efficient traversal of k‐space and hardware
limitations, or other physical effects can cause the k‐space trajectory to deviate from a …

Purpose To develop a simple and robust tool for the estimation of gradient delays from
highly undersampled radial k‐space data. Theory In radial imaging gradient delays induce …

Background and purpose Physiological motion impacts the dose delivered to tumours and
vital organs in external beam radiotherapy and particularly in particle therapy. The excellent …

Purpose To measure temperature over a large brain volume with fine spatiotemporal
resolution. Methods A three‐dimensional stack‐of‐stars echo‐planar imaging sequence …

Radial sampling pattern is an important signal acquisition strategy in magnetic resonance
imaging (MRI) owing to better immunity to motion-induced artifacts and less pronounced …

Purpose To correct gradient timing delays in non‐Cartesian MRI while simultaneously
recovering corruption‐free auto‐calibration data for parallel imaging, without additional …

Spiral imaging is very well suited for functional MRI, however its use has been limited by the
fact that artifacts caused by gradient imperfections and B 0 inhomogeneity are more difficult …

Purpose Real‐time monitoring of dynamic magnetic fields has recently become a
commercially available option for measuring MRI k‐space trajectories and magnetic fields …

Purpose To reconstruct artifact‐free images from measured k‐space data, when the actual k‐
space trajectory deviates from the nominal trajectory due to gradient imperfections. Methods …
