PROBLEM TO BE SOLVED: To provide a medical image diagnostic apparatus which accurately displays a region that an operator wants to see by producing a three-dimensional partial image of a treatment member in a real time fashion.SOLUTION: The medical image diagnostic apparatus includes a treatment member image producing section that produces in a real time fashion a three-dimensional image of a treatment member on the basis of a two-dimensional first transmission image and second transmission image including the treatment member and produced on the basis of two-dimensional transmission images, a region restricting section that restricts data regions of three-dimensional transmission data and the two-dimensional transmission data to predetermined regions, an image synthesis section that superimposes a blood vessel partial image produced by using the restricted three-dimensional transmission data on a treatment member partial image produced by using the restricted two-dimensional transmission data, and an image display section that displays the superimposed blood vessel partial image and the treatment member partial image.COPYRIGHT: (C)2011,JPO&INPIT【課題】3次元の処置用部材像の一部をリアルタイムに生成し、見たい箇所を精度良く表示させることが可能な医用画像診断装置を提供する。【解決手段】2次元の透視データを基に、処置用部材を含む2次元の第1透視像及び第2透視像を基に、3次元の処置用部材像をリアルタイムに生成する処置用部材像生成部と、3次元の透視データ及び2次元の透視データを予め定められた領域に限定する領域限定部と、限定された前記3次元の透視データを用いて生成される前記血管像の部分、及び、限定された前記2次元の透視データを用いて生成される前記処置用部材像の部分を重ね合わせる画像合成部と、重ね合わされた血管像の部分及び処置用部材像の部分を表示する画像表示部と、を有する。【選択図】図2
