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

Transmission Performance of Halbach Array Cylindrical Permanent Magnet Governor
Electronics (Switzerland), 2023 A novel cylinder permanent magnet governor (CPMG) with Halbach segmentation is proposed in this paper. In order to improve the transmission performance of the CPMG, different permanent magnet (PM) arrangement methods are adopted. To achieve a fair comparison result, all the PMs are of the same size.
