Abstract:
1. An MR image production method comprising: a calibration scan step of 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; a real scan step of 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; a synthesis step of 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 a water image-fat image separation step of producing at least one of a water image and a fat image from the synthetic image.
