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...

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...

Method and Apparatus to Improve an MRI Image

The invention is a method for improving image quality in MR imaging methods using the SENSE (SENSitivity Encoding) method, which is known to have degraded image quality due to numerical ill-conditioning (so called g-factor loss). The invention improves the numerical conditioning by means of an adaptive regularization (matrix conditioning), thereby improving...

Mapping Internal and Bulk Motion of an Object with Phase Labeling in Magnetic Resonance Imaging

Current MRI methods for tracking the motion of an object over a relatively long period of time requires the use of precisely defined grid points that may be inexact because of limited image resolution or the size of the element being tracked. Phase contrast velocity mapping generally provides high spatial resolution and simple data processing. However,...
