  • Water-fat separation for fast spin echo imaging in an inhomogeneous field with progressive encoding
    Patent number: 7141972
    Abstract: A method to separate two chemically-shifted components of water (w) and fat (f) signals by: (i) estimating the field inhomogeneity ? through a treatment of the residuals of the Moore-Penrose solution of the following equations: cos(?n?)*w+cos [?n(1+?)]*f=real (In) and sin(?n?)*w+sin [?n(1+?)]*f=imaginary (In), and (ii) using the estimated ? to determine the resulting solution for w and f from the original input signals In.
