Method For Producing Spectral-Spatial Parallel Rf Excitation Pulses For Magnetic Resonance Imaging
view source
US Patent:

20100156411, Jun 24, 2010
Filed:

Aug 20, 2009
Appl. No.:

12/544714
Inventors:

Kawin Setsompop - Cambridge MA, US
Borjan A. Gagoski - Cambridge MA, US
Elfar Adalsteinsson - Belmont MA, US
Vijayanand Alagappan - Streetsboro OH, US
Lawrence L. Wald - Cambridge MA, US
International Classification:

G01R 33/44
US Classification:

324307
Abstract:

A method for producing a spatially and spectrally selective radiofrequency (“RF”) excitation pulse includes establishing a desired spatial RF excitation pattern and establishing a desired spectral RF excitation pattern. The method also includes estimating an RF transmission profile map indicative of the transmission characteristics of an RF coil and determining, from the desired spatial and spectral excitation patterns and the estimated RF transmission profile map, at least one magnetic field gradient waveform indicative of locations in k-space to which RF energy is to be deposited. The method further includes determining, from the established spatial and spectral excitation patterns, the estimated RF transmission profile map, and the determined at least one gradient waveform, at least one RF excitation pulse waveform that will produce the desired spatial and spectral excitation patterns.

US Patent:

20120146639, Jun 14, 2012
Filed:

Sep 20, 2011
Appl. No.:

13/237799
Inventors:

Alma Gregory Sorensen - Belmont MA, US
Ovidiu Cristian Andronesi - Melrose MA, US
Carolyn Mountford - , US
Saadallah Ramadan - Bexley, AU
Borjan Aleksandar Gagoski - Cambridge MA, US
Elfar Adalsteinsson - Belmont MA, US
International Classification:

G01R 33/44
US Classification:

324309
Abstract:

Methods for low-power in vivo localized multi-dimensional correlated magnetic resonance spectroscopy (“MRS”) are provided. Low-power adiabaticity is achieved, generally, using gradient-modulated radio frequency pulses for localization and mixing. The provided pulse sequences also provide a mechanism for longitudinal mixing, which significantly increases the efficiency of magnetization transfer and thereby increases signal-to-noise ratio.
