Purpose The gradient system transfer function (GSTF) has been used to describe the
distorted k‐space trajectory for image reconstruction. The purpose of this work was to use …

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 …

Purpose In radial imaging, projections may become “miscentered” due to gradient errors
such as delays and eddy currents. These errors may result in image artifacts and can disrupt …

Purpose To estimate k‐space trajectory errors in non‐Cartesian acquisitions and reconstruct
distortion‐free images, without trajectory measurements or gradient calibrations. Theory and …

Purpose The gradient system transfer function (GSTF) characterizes the frequency transfer
behavior of a dynamic gradient system and can be used to correct non‐Cartesian k‐space …

With the advent of ultra‐high field MRI scanners in clinical research, susceptibility based
MRI has recently gained increasing interest because of its potential to assess subtle tissue …

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 Carotid artery imaging is important in the clinical management of patients at risk for
stroke. Carotid intraplaque hemorrhage (IPH) presents an important diagnostic challenge …
