  • Image intensity correction for magnetic resonance imaging
    Patent number: 9036884
    Abstract: A magnetic resonance system includes a magnetic resonance scanner having a multi-channel transmit coil or coil system and a magnetic resonance receive element; and a digital processor configured to perform an imaging process. The image process includes shimming the multi-channel transmit coil or coil system, acquiring a coil sensitivity map for the magnetic resonance receive element using the multi-channel transmit coil or coil system, acquiring a magnetic resonance image using the magnetic resonance receive element and the shimmed multi-channel transmit coil or coil system, and performing an intensity level correction on the acquired magnetic resonance image using the coil sensitivity map to generate a corrected magnetic resonance image.
    Type: Grant

  • CONCURRENT OPTIMIZATION OF RF POWER AND RF FIELD UNIFORMITY IN MRI
    Publication number: 20120161766
    Abstract: A magnetic resonance method comprising: loading a subject into a magnetic resonance scanner; with the subject loaded into the magnetic resonance scanner, acquiring B1 maps (72) for a plurality of radio frequency transmit channels of the magnetic resonance scanner; shimming the plurality of radio frequency transmit channels and setting a radio frequency transmit power for the shimmed plurality of radio frequency transmit channels using the acquired B 1 maps to generate optimized amplitude and phase parameters (98) for the plurality of radio frequency transmit channels; acquiring magnetic resonance imaging data of the subject loaded into the magnetic resonance scanner including exciting magnetic resonance by operating the plurality of radio frequency transmit channels using the optimized amplitude and phase parameters; generating a reconstructed image from the acquired magnetic resonance imaging data; and displaying the reconstructed image.
