  • Flexible radio frequency coil array with detachable straps for MR imaging
    Patent number: 10969447
    Abstract: Methods and systems are provided for radio frequency (RF) coil arrays for magnetic resonance imaging (MRI) systems. In an embodiment, a RF coil array assembly for a MRI system includes a compressible body; an upper posterior RF coil array including a first plurality of RF coils embedded in the compressible body; a lower posterior RF coil array including a second plurality of RF coils embedded in the compressible body; and a head and neck RF coil array removably coupled to the upper posterior RF coil array. The head and neck RF coil array includes a third plurality of RF coils embedded in the compressible body, and one or more neck straps configured to fold over a neck of a subject to be imaged by the MRI system.

  • System and method for magnetic resonance radio-frequency field mapping
    Patent number: 8558547
    Abstract: A system and method for radio-frequency (RF) field mapping are provided. One method includes encoding a B1 phase in at least one magnetic resonance (MR) excitation pulse as an encoded B1 phase MR excitation pulse for at least a subset of a plurality of transmit channels within a magnetic resonance imaging (MRI) system. The method also includes encoding a B1 magnitude in at least one off-resonance MR pulse as an encoded B1 magnitude off-resonance MR pulse for at least a subset of the plurality of transmit channels within the MRI system. The method further includes determining one or more composite B1 fields resulting from a transmission of the at least one encoded B1 phase MR excitation pulse and the at least one encoded B1 magnitude off-resonance MR pulse.
