Magnetic resonance imaging apparatus

Abstract

For the purpose of providing a magnetic resonance imaging apparatus for capturing water/fat-separated images free of banding artifacts in an SSFP state, an apparatus comprises: acquiring means (202) for acquiring echo data of a plurality of views in which a phase difference between water and fat is 2π/m with spins within a subject brought to the SSFP state and repeating the acquisition for k=0 through M−1 with a step difference in a phase of an RF pulse of 2π·k/M; transforming means (204) for conducting Fourier transformation on the echo data based on the phase step difference; separating means (206) for separating water data and fat data respectively in F(0) term and F(1) term of the Fourier-transformed data using the phase difference between water and fat; adding means (208′) for obtaining a sum of absolute values of at least the water data or fat data in the F(0) term and F(1) term; and image producing means (210′) for producing an image based on the sum data.
