  • System and method for externally calibrated parallel imaging in the presence of an inhomogeneous magnetic field
    Patent number: 9989613
    Abstract: A system and method for accelerated magnetic resonance imaging (MRI) includes controlling an RF system of an MRI system to acquire coil calibration data from a subject including a material causing inhomogeneities in a static magnetic field of the MRI system when arranged in the bore of the MRI system. After acquiring the coil calibration data, the RF system is controlled to acquire imaging data from the subject at multiple different resonance frequency offsets. The spectral bin images relate specific resonance frequencies to distinct spatial locations in the static magnetic field of the MRI system. An image of the subject is reconstructed from the imaging data using coil calibration data and the spectral bin data to provide spatial encoding of the image.
