Furthermore lightens the burden to the suffering inspection body with the fluctuation of drift speed of the bed the MRI device which moving bed image pickup occasion, it is possible, to do the modification of image pickup on off and the image pickup condition by the organism synchronization signal is offered. As for the control means which control with the bed which conveys the suffering inspection body in magnetostatic field and the expedient which impresses the RF magnetic field and the inclined magnetic field because of image pickup, as drift speed of the bed is set to one constant speed which considers all the image pickup times, in order the image pickup range of vision in suffering inspection body system of coordinates (the image pickup territory) drift speed) to make differ from the drift speed of the bed, magnetic field impression expedient of the RF magnetic field and the inclined magnetic field is controlled.ムービングベッド撮像の際に、生体同期信号による撮像のオンオフや撮像条件の変更を行なうことができ、しかもベッドの移動速度の変動による被検体への負担を軽減したMRI装置を提供する。被検体を静磁場中で搬送するベッドと撮像のためのRF磁場及び傾斜磁場を印加する手段とを制御する制御手段は、ベッドの移動速度を全撮像時間を考慮した一定速度に設定するとともに、被検体座標系における撮像視野(撮像領域)の移動速度)をベッドの移動速度と異ならせるようにRF磁場及び傾斜磁場の磁場印加手段を制御する。
