Abstract
Systems and methods for combined ghost artifact correction and parallel imaging reconstruction of simultaneous multislice (“SMS”) magnetic resonance imaging (“MRI”) data are provided. Dual-polarity training data are used to generate ghost-free slice data, which are used as target data in a reconstruction kernel training process. The training data are used as source data in the reconstruction kernel training. As a result, reconstruction kernels are computed, which can be used to reconstruct images from SMS data in which slice-specific ghosting artifacts are removed.
