A variety of applications and research directions in magnetic resonance imaging which
require fast scan times have recently become popular. In order to satisfy many of the …

In this article, several theoretical and methodological developments regarding k‐space‐
based, locally constrained parallel MRI (pMRI) reconstruction are presented. A connection …

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

Abstract Magnetic Resonance Imaging (MRI) is an essential technology in modern
medicine. However, one of its main drawbacks is the long scan time needed to localize the …

The imaging of dynamic processes in the body is of considerable interest in interventional
examinations as well as kinematic studies, and spiral imaging is a fast magnetic resonance …

A variant of periodically rotated overlapping parallel lines with enhanced reconstruction
(PROPELLER) MRI, called turboprop, is introduced. This method employs an oscillating …

Parallel imaging (PI) is one of the most promising recent advances in MRI technology and
has, similar to the introduction of multidetector helical scanning in CT, revolutionized MR …

A novel technique called “k‐t GRAPPA” is introduced for the acceleration of dynamic
magnetic resonance imaging. Dynamic magnetic resonance images have significant signal …

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 …

Purpose The purpose of this work is to explore the feasibility and performance of single‐shot
spiral MRI at 7 T, using an expanded signal model for reconstruction. Methods Gradient …
