Abstract: Magnetic resonance images with improved image quality consistent with those obtained using parallel radio frequency (“RF”) transmission (“pTx”) techniques are generated from data acquired using single transmission hardware (e.g., single channel RF transmission). A deep-learning framework is used to train a deep neural network to convert images obtained with single transmission into pTx-like images. The pTx-like images have reduced signal variations and dropouts that may otherwise be attributable to B1+ inhomogeneities.
