We propose an Attention Based Scale Recurrent Network for reconstructing under-sampled MRI data. This network is a variation of the recently proposed Scale Recurrent Network for blind deblurring¹. We treat the reconstruction problem as a deblurring problem. Thus the under-sampling pattern does not need to be known. We trained and tested our network with the NYU knee dataset available for the fastMRI challenge. The proposed model shows promising results for single-coil reconstruction outperforming both baselines.
