Patent ID: 8503751

Claim:
A method for implementing fat-water separation, comprising the steps of: acquiring an in-phase image and two out-of-phase images of a subject; in a processor, automatically calculating phase differences between the two out-of-phase images, and correcting the phases caused by the inhomogeneity of a magnetic field in the two out-of-phase images by using the phase differences; in a processor, automatically correcting linear phase differences caused by eddy currents in the in-phase image by using the two corrected out-of-phase images by calculating a result S 32 of (S 3 ′×S 2 *)×(S 2 ×S 1 ′*)* to obtain a phase φ ecc corresponding to S 32 ; wherein S 2 represents the acquired in-phase image, S 1 ′ and S 3 ′ represent the two corrected out-of-phase images, and * represents the conjugate operation, and multiplying S 2 by φ ecc to obtain an in-phase image S 2 ′ after correction; and in a processor, making calculations based on the three corrected images to obtain water and fat images.
