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.
