PROBLEM TO BE SOLVED: To provide the nuclear magnetic resonance imaging apparatus which can obtain stable MR image even at picture taking condition at the signal phase variation is changed from moment to moment, according to the change of saturation state of eddy current and spin. SOLUTION: The scanned data which consists of a plurality of nuclear magnetic resonance signals, are obtained continuously by changing slice encoded gradient magnetic field or phase encoded gradient magnetic field, to obtain series of regular scanning data. At that time, the scanning data for correction are obtained repeatedly at nearly the same time intervals during period of obtaining a series of scanning data. The correcting data, containing time variation between scanning data for correction and next obtained scanning data for correction, are prepared using this correcting data. A series of regular scanning data are corrected by using this correcting data. EPI image is obtained stable even at picture taking condition which signal phase variation is changed from moment to moment, since the regular scanning data are always corrected by the phase rotation estimated value at obtained time. |
