Summary:PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging apparatus capable of generating a joined image in which images are continuously joined to each other even if cross sections of a plurality of non-coplanar cross-sectional images do not intersect with each other.SOLUTION: The magnetic resonance imaging apparatus 10 comprises: a static magnetic field generation unit for generating a static magnetic field; a gradient magnetic field generation unit for generating a gradient magnetic field; a transmission coil for applying a high frequency pulse to a subject; original-image generation means 43 for generating a plurality of non-coplanar cross-sectional images on the basis of a signal corresponding to the high frequency pulse; joined-cross section setting means 44 for setting a new cross section different from any of the cross sections of the plurality of cross-sectional images and for setting a joined cross section on the basis of at least one of the cross sections of the plurality of cross-sectional images and the new cross section; joining-target image generation means 45 for generating cross-sectional images relating to the cross sections comprising the joined cross section; and joined-image generation means 46 for generating a joined image by applying join processing to the cross-sectional images relating to the joined cross section.SELECTED DRAWING: Figure 2 【課題】磁気共鳴イメージング装置において、同一平面上にない複数の断面画像の断面が交差しない場合であっても、像が連続的な結合画像を生成することができる。【解決手段】磁気共鳴イメージング装置１０は、静磁場を発生する静磁場発生部と、傾斜磁場を発生する傾斜磁場発生部と、被検体に高周波パルスを印加する送信用コイルと、前記高周波パルスに対応する信号に基づいて、同一平面上にない複数の断面画像を生成する原画像生成手段４３と、複数の断面画像のいずれの断面とも異なる新断面を設定し、複数の断面画像の断面のうち少なくとも一つと、新断面とに基づいて結合断面を設定する結合断面設定手段４４と、結合断面を構成する各断面に係る断面画像を生成する結合対象画像生成手段４５と、結合断面に係る各断面画像に対して結合処理を行なうことで結合画像を生成する結合画像生成手段４６と、を有する。【選択図】 図２
