Radial TRASE: 2D RF encoding through mechanical rotation and active digital decoupling. [PDF]

Magn Reson Med
Abstract Purpose Two‐dimensional (2D) transmit array spatial encoding (TRASE) previously required four radiofrequency fields; however, interactions between transmit (Tx) array elements caused significant challenges for 2D imaging. Here, we present a low‐cost, 2D radial encoding scheme (Radial TRASE) using a simplified two‐coil array.

Open-Source Multinuclear Low-Field Preclinical MRI Scanner. [PDF]

NMR Biomed
A step‐by‐step guideline for the construction of an open‐source multinuclear low‐field MRI scanner for preclinical studies is presented together with the first images acquired with the device. The scanner can detect 1H, 23Na, hyperpolarized 13C, and 15N signals at 66 mT. ABSTRACT Low‐field MRI (B0 ≤ 0.2 T) is emerging as a technology with the potential

An Analytical Study on the Magnetic Levitation System Using a Halbach Magnet Array [PDF]

Transactions of the Korean Society for Noise and Vibration Engineering, 2007
Typically, three types of levitation technologies are applied to magnetic levitation systems: electromagnetic suspension, electrodynamic suspension, and hybrid electromagnetic suspension. A Halbach array is a special arrangement of permanent magnets which augments the magnetic field on one side of the device while cancelling the field to near zero on ...

Porous Hybrid Soft Actuators From Liquid Crystal Networks and Lyotropic Chromonic Liquid Crystal Templated Hydrogels. [PDF]

Adv Mater
The graphic illustrates the design of a hybrid bilayer composed of a liquid crystal hydrogel (LCH) and a liquid crystal network (LCN). The figure highlights the magnetic alignment of the chromonic hydrogel and the thermal‐responsive actuation of the LCN along with the LCH when both layers are aligned or misaligned, enabling programmable, light‐driven ...

The Effect of Magnet Magnetization Vector Orientation in Halbach Arrays on the Effectiveness of Separation

Acta Physica Polonica A, 2014
Magnetic separation is one of the methods that are used to separate magnetic and non-magnetic components from an input mixture. Its e ectiveness strongly depends on the strength and distribution of magnetic eld in the separator. It is economical to use Halbach permanent magnet arrays to create a suitable magnetic eld, since they do not change their ...
