Recently, deep learning methods have shown superior performance on image reconstruction and noise suppression by implicitly yet effectively learning prior information. However, end-to-end deep learning methods face the challenge of potential numerical instabilities and require complex application specific training. By taking advantage of the multichannel spatial encoding (as exploited by conventional parallel imaging reconstruction) and prior information (exploited by deep learning methods), we propose to embed a deep learning module into the iterative low-rank matrix completion based image reconstruction. Such strategy significantly suppresses the noise amplification and accelerates iteration convergence without image blurring.
