摘要:
Generating the high frequency magnetic field and the inclined magnetic field in magnetostatic field occurrence expedient and the aforementioned photographing space which generate magnetostatic field in the photographing space, measurement expedient and the aforementioned nuclear magnetic resonance signal which measure the nuclear magnetic resonance signal where the suffering inspection body which is arranged in the aforementioned photographing space occurs on the basis of, in the magnetic resonance imaging device which has the indicatory expedient which indicates the magnetic resonance picture which is obtained by control means and the aforementioned signal processing expedient which control signal processing expedient and the aforementioned measurement expedient and the aforementioned signal processing expedient which reconstruct the magnetic resonance picture, Depending on the quality of the aforementioned magnetostatic field occurrence expedient, depending on the organization of 1st information and the aforementioned suffering inspection internal you display the unevenness distribution of the magnetostatic field which it occurs the memory expedient which remembers the 2nd information which displays the unevenness distribution of the magnetostatic field which it occurs and the revision magnetic field occurrence expedient which generates the revision magnetic field the photographing range of vision in the territory of desire of the aforementioned suffering inspection body inside and the description above setting expedient and the aforementioned 2nd information which set the information which corresponds to the photographing range of vision which is set as 3rd information on the basis of selective expedient and the aforementioned 3rd information and the aforementioned 1st information which it selects,It has.撮影空間に静磁場を発生する静磁場発生手段と、前記撮影空間に高周波磁場及び傾斜磁場を発生して、前記撮影空間に配置された被検体が発生する核磁気共鳴信号を計測する計測手段と、前記核磁気共鳴信号を基に、磁気共鳴画像を再構成する信号処理手段と、前記計測手段及び前記信号処理手段を制御する制御手段と、前記信号処理手段により得られた磁気
