In view of recent applications in cardiovascular and functional brain imaging, this work
revisits the basic performance characteristics of spiral imaging in direct comparison to echo …

The effect of in‐plane motion on the point spread function (velocity PSF) in spiral imaging is
studied experimentally and derived mathematically and is shown to consist of a smoothed …

The use of self‐calibrating techniques in parallel magnetic resonance imaging eliminates
the need for coil sensitivity calibration scans and avoids potential mismatches between …

A new approach to autocalibrating, coil‐by‐coil parallel imaging reconstruction, is
presented. It is a generalized reconstruction framework based on self‐consistency. The …

Spiral acquisition schemes offer unique advantages such as flow compensation, efficient k-
space sampling and robustness against motion that make this option a viable choice among …

A variable‐density spiral k‐space trajectory is introduced for brain functional magnetic
resonance imaging. The proposed spiral trajectory consists of an Archimedean spiral from …

A self‐calibrated parallel imaging reconstruction method is proposed for azimuthally
undersampled radial dataset. A generalized auto‐calibrating partially parallel acquisition …

A modified spiral imaging technique is presented, in which the conventional sinusoidal
gradient waveforms are replaced by trapezoidal ones. In addition to allowing a reduced data …

Spiral trajectories offer a number of attractive features for fast imaging. A practical problem
for the implementation on routine magnetic resonance scanners is the lack of appropriate …
