PROBLEM TO BE SOLVED: To easily acquire the radiation image including an examination object even if the displacement of the examination object is caused by the puncture of a sampling needle when a biopsy is executed.SOLUTION: A mammography apparatus 10 includes a radiation source 24, a collimator 25, and a radiation controller 134. The radiation controller 134 changes the position of the flash coverage of a radiation 22 which is set so that the distal end of a biopsy needle 50 and a biopsy site may be fitted, along the puncture direction of the biopsy needle 50 by an irradiation range moving part, when a radiation image is acquired in a state in which the biopsy needle 50 is punctured in a mammo 20.COPYRIGHT: (C)2013,JPO&INPIT【課題】バイオプシを実施において採取針の穿刺により検査対象物の位置ずれが生じても該検査対象物を含む放射線画像を簡単に取得する。【解決手段】マンモグラフィ装置10は、放射線源24と、コリメータ25と、放射線制御部134と、を有する。放射線制御部134は、生検針50をマンモ20に穿刺した状態において放射線画像を取得する場合に、照射範囲移動部により、生検針50の先端部と生検部位が収まるように設定された放射線22の照射範囲の位置を生検針50の穿刺方向に沿って変更する。【選択図】図9
