PROBLEM TO BE SOLVED: To provide an MRI apparatus that has reduced vibration of a bed top plate transmitted from a floor through a bed body.SOLUTION: A magnetic resonance imaging apparatus includes: a gantry having a static magnetic field generating system for generating a static magnetic field space, a gradient magnetic field generating system for generating a gradient magnetic field in the static magnetic field space, and a high frequency transmission coil for irradiating an object to be examined with a high frequency signal a bed body arranged in parallel with the gantry and a bed top plate provided on the bed body so as to be horizontally movable, on which the object to be examined is placed and sent to an imaging space of the gantry. The bed body includes a top plate receiver that supports the bed top plate and slides, and the bed top plate and the top plate receiver are provided with a vibration suppression part for suppressing the vibration of the bed top plate.COPYRIGHT: (C)2015,JPO&INPIT【課題】床から寝台本体を介して伝わる寝台天板振動を低減したMRI装置を提供することである。【解決手段】静磁場空間を発生する静磁場発生系と、静磁場空間内に傾斜磁場を生成する傾斜磁場発生系と、被検体に高周波信号を照射する高周波送信コイルとを有するガントリ、及びガントリに並設されている寝台本体と、寝台本体上に水平移動可能に設けられ、被検体を載せてガントリの撮像空間内に送り込む寝台天板とを備え、寝台本体は、寝台天板を支持し摺動する天板受けを有し、寝台天板および天板受けに、寝台天板の振動を抑制する振動抑制部を設けたことを特徴とする。【選択図】図2A
