Multilayered RF Coil System for Improving Transmit B1 Field Homogeneity in High-Field MRI
Available for licensing and commercial development is a multilayered radio-frequency (RF) coil system for improving the transmit B1 field homogeneity for magnetic resonance imaging (MRI) at high field strengths. The current invention aims at manipulating the inhomogeneous profile of the transmit B1 field, which causes MR images to become less uniform...

A Novel Magnetic Resonance Radio-Frequency Coil Array that Eliminates Inductive Coupling
Parallel magnetic resonance imaging (MRI) techniques employ RF coil arrays for faster data acquisition, and have been shown to reduce the overall length of MRI procedures, improve signal-to–noise ratio (SNR) and image quality, thus making MRI more attractive and less costly. Elimination of inductive coupling is an essential step in designing RF coil...

Snapshot Spatial Heterodyne Imaging Polarimetry
A real time imaging Stokes polarimeter that is able to render the full linear polarization profile of a scene without the need for computational support has been designed the University of Arizona. This polarization imaging is achieved through an advanced optical design that requires no moving parts. It uses the full spectral content of a scene to form...
