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...

System for Correction of MRI Head Motion
Motion artifacts continue to be a significant problem in MRI of human brain. Prospective motion correction based on external tracking systems has been proposed to ameliorate this issue. However, the calibration of these systems is very complicated and time consuming, as it requires a camera system calibration as well as a calibration between camera...

Method For Proton Magnetic Resonance Spectroscopic Imaging With Multiple Spin-Echoes
This application describes a new method for proton magnetic resonance spectroscopic imaging. This new method does not have the limiting disadvantages of the previous techniques. The method combines multi-slice and multi-spin-echo techniques for high signal-to-noise ratio per unit time and high efficiency spectroscopic information. This invention can...

Ultrafast Burst Imaging Using Shifting Of Excited Regions
This invention is a new three-dimensional magnetic resonance imaging device that will allow better imaging of biologic tissue. Conventional BURST technology excites a set of equally spaced, narrow strips in an object and creates an image from a single slice, perpendicular to the direction of the strips. In order to scan multiple slices or for three-dimensional...
