PROBLEM TO BE SOLVED: To reduce an SAR (Specific Absorption Ratio) or reduce nonuniformity of B1 distribution in an MRI apparatus in a high magnetic field.SOLUTION: The magnetic resonance imaging apparatus adjusts a posture of a subject 103a or 103b in imaging to such an extent that it is not the burden on a patient as the subject, and improves at least one of a local specific absorption ratio of a prescribed site and uniformity of a high frequency magnetic field distribution of a region of interest, more than that of before the adjustment. The adjustment is performed by a posture adjusting member 121 provided in the MRI apparatus. The posture adjusting member 121 is arranged on a table 107 on which the subject is placed and can change the arrangement position and/or height.COPYRIGHT: (C)2016,JPO&INPIT【課題】高磁場のMRI装置において、SARの低減、もしくは、B1分布の不均一の低減を行う。【解決手段】被検体である患者に大きな負担とならない範囲で、撮像時に被検体103a,bの姿勢を調整し、所定の部位の局所比吸収率および関心領域の高周波磁場分布の均一度の少なくとも一方を、調整前より向上させる。調整は、MRI装置が備える姿勢調節部材121によりなされる。姿勢調節部材121は、被検体を載置するテーブル107上に配置され、配置位置および/または高さを変更可能な部材とする。【選択図】図7
