By the method of integrating the total variation regularized iterative reconstruction and water fat separation calculation, the water and fat images with robust and high quality is reconstructed from the undersampled TSE BLADE three point Dixon with less scanning time comparing with full coverage of BLADE k-space trajectory. The final fat and water images have less streaking artifacts comparing with conventional regridding reconstruction methods followed by water-fat separation. Meanwhile, inheriting the benefits of the BLADE scanning, the present method is less sensitive to the motions comparing with Cartesian sampling.
