Patent ID: 7336986

Claim:
A magnetic resonance imaging apparatus comprising: an acquiring device for acquiring echo data of a plurality of views with spins within a subject brought to an SSFP state and repeating the acquisition for k=0 through M−1 (M being an integer not less than two; k=0, 1, . . . , M−1) with a step difference in a phase of an RF pulse of 2π·k/M; a transforming device for conducting Fourier transformation on the echo data based on said phase; a separating device that corrects a phase error by a phase distribution multiplied by 1/m, after multiplying the phase of the Fourier-transformed data by m to make water and fat in phase and correcting wraparound of a portion beyond a range of ±π, an adding device for obtaining a sum of absolute values of F(0) term and F(1) term of the Fourier-transformed data; and an image producing device for producing an image based on the sum data.
