The use of spiral trajectories is an efficient way to cover a desired k‐space partition in
magnetic resonance imaging (MRI). Compared to conventional Cartesian k‐space …

MRI with non‐Cartesian sampling schemes can offer inherent advantages. Radial
acquisitions are known to be very robust, even in the case of vast undersampling. This is …

Generalized autocalibrating partially parallel acquisitions (GRAPPA), an important parallel
imaging technique, can be easily applied to radial k‐space data by segmenting the k‐space …

This work describes an auto‐calibrated method for parallel imaging with spiral trajectory.
The method is ak‐space approach where an interpolation kernel, accounting for coil …

In this work an iterative reconstruction method based on generalized autocalibrating partially
parallel acquisitions (GRAPPA) reconstruction is introduced. In the new method the …

In this study, a novel partially parallel acquisition (PPA) method is presented which can be
used to accelerate image acquisition using an RF coil array for spatial encoding. This …

Current parallel imaging techniques for accelerated imaging require a fully encoded
reference data set to estimate the spatial coil sensitivity information needed for …

Accelerated parallel MRI has advantage in imaging speed, and its image quality has been
improved continuously in recent years. This paper introduces a two‐dimensional infinite …

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 fast parallel MRI (pMRI) reconstruction method is presented for 2D and 3D radial
trajectories. A limitation of the radial generalized autocalibrating partially parallel …
