Compressed sensing method and its variations have been developed for reconstruction of MRI using undersampled k space data. Here we propose a constraint dedicated for diffusion tensor imaging (DTI) as well as a phase constraint that has been used in partial Fourier reconstruction to improve compressed sensing reconstruction accuracy. The testing result on high field mouse embryo DTI shows improvement of reconstruction accuracy in both diffusion weighted (DW) and tensor images.
