While having with the expedient which generates each magnetic field of magnetostatic field, the inclined magnetic field and the high frequency magnetic field and the expedient which receives the echo signal which occurs from the suffering inspection body, the echo data which corresponds to the measurement locus of 1 or more in the k space, changing the angle for the k spatial axis of coordinates of the said measurement locus to measure, with the photographing expedient which at least collects one measurement data in every angle and to rearrange the aforementioned measurement data in the k space and picture reconstruction expedient to precede the rearrangement of the measurement data to the k space the picture the picture reconstruction expedient which is reconstructed in the MRI device which has, angleEvery, the standard data which is selected from the measurement data phase for revision is calculated on the basis of, the measurement data phase is revised making use of the phase for revision which was calculated. Because of this non-linearity and the arch fact which the magnetic field of the inclined magnetic field uneven originates is decreased without extending photographing time.静磁場、傾斜磁場および高周波磁場の各磁場を発生する手段と、被検体から発生するエコー信号を受信する手段とを備え、k空間における1以上の計測軌跡に対応するエコーデータを、該計測軌跡のk空間座標軸に対する角度を変えながら計測し、角度毎に少なくとも一つの計測データを収集する撮影手段と、前記計測データをk空間に再配置し画像再構成する画像再構成手段とを備えたMRI装置において、画像再構成手段は、k空間への計測データの再配置に先立ち、角度毎に、計測データから選択した基準データをもとに補正用位相を算出し、算出された補正用位相を用いて計測データを位相補正する。これにより撮影時間を延長することなく、傾斜磁場の非線形性や磁場不均一に起因するアーチファクトを低減する。
