Parallel magnetic resonance imaging (pMRI) is a technique to accelerate the magnetic resonance imaging process. The problem of reconstructing an image from the collected pMRI data is ill-posed. Regularization on multi-coil images by tight-frame systems is proposed to reduce the aliasing artifacts on reconstructed images. Numerical experiments for in-silico and in-vivo data sets are provided to demonstrate the superiority of the 3-D regularization model and the efficiency of our proposed algorithm for pMRI reconstruction.
