ABSTRACT:
A method to generate separate water and fat images includes applying a pulse sequence, which brings about no phase difference between a water signal and a fat signal, so as to acquire calibration data items that provide the distribution of sensitivities of coils, applying a pulse sequence, which uses the phase difference between a water signal and a fat signal to separate the signals from each other, so as to receive NMR signals, which are induced by a subject, in parallel with one another using I (≧2) coils, and acquiring real data items detected by the respective coils, producing a synthetic image by performing arithmetic operations on the calibration data items and the real data items detected by the respective coils so as to remove aliasing oriented in a phase encoding direction, and producing at least one of a water image and a fat image from the synthetic image.
