Reconstructed MR images on the fastMRI brain dataset from the 4x accelerated 1DEU pattern. (a) denotes the ground truth image; (b–e) denote the reconstructed images of SPIRiT, Deepcomplex, DONet, and SPIRiT-Net, respectively; (f) denotes the undersampling pattern (1DEU); and (g–j) denote corresponding error maps of reconstructed images.
