Permanent magnet arrays offer several attributes attractive for the development of a low-cost
portable MRI scanner for brain imaging. They offer the potential for a relatively lightweight …

Purpose As the premiere modality for brain imaging, MRI could find wider applicability if
lightweight, portable systems were available for siting in unconventional locations such as …

Three-dimensional MRI has gained increasing popularity in various clinical applications due
to its improved through-plane spatial resolution, which enhances the detection of subtle …

Portable low-cost magnetic resonance imaging (MRI) systems have the potential to enable
“point-of-care” and timely MRI diagnosis, and to make this imaging modality available to …

Purpose Nonlinear spatial encoding magnetic fields (SEMs) have been studied to
reconstruct images from a minimum number of echoes. Previous work has also explored …

We present a design and the optimization of an irregular-shaped inward-outward (IO) ring-
pair magnet array that generates a 1D monotonic field pattern for 2D head imaging in a low …

Magnetic resonance imaging (MRI) is a powerful noninvasive diagnostic tool with superior
soft tissue contrast. However, access to MRI is limited since current systems depend on …

To date, spatial encoding for MRI is based on linear X, Y and Z field gradients generated by
dedicated X, Y and Z wire patterns. We recently introduced the dynamic multi‐coil technique …

Purpose Nonlinear spatial encoding magnetic (SEM) field strategies such as O‐space
imaging have previously reported dispersed artifacts during accelerated scans. Compressed …

Abstract Fast ROtary Nonlinear Spatial ACquisition (FRONSAC) was recently introduced as
a new strategy that applies nonlinear gradients as a small perturbation to improve image …
