PROBLEM TO BE SOLVED: To provide a mammography apparatus that has improved visibility of calcification without changing a burden of a pain on a medical examinee during the compression of the breast.SOLUTION: A mammography apparatus 1 includes an X-ray tube 21a for irradiating an X-ray, an FPD 22c for detecting the X-ray, a movement mechanism for supporting the X-ray tube 21a and moving the X-ray tube 21a, and a tomosynthesis imaging function 31d for performing tomosynthesis imaging by controlling the X-ray tube and the X-ray detector so as to perform the imaging a plurality of times intermittently, and controlling the movement mechanism 24 so that a movement speed of the X-ray tube 21a changes during a period from the start of the initial imaging to the end of the last imaging of the plurality of times of imaging.SELECTED DRAWING: Figure 5 【課題】乳房Ｘ線撮影装置において、乳房圧迫による受診者への痛みの負担を変えることなく、石灰化の視認性を向上させること。【解決手段】乳房Ｘ線撮影装置１は、Ｘ線を照射するＸ線管２１ａと、Ｘ線を検出するＦＰＤ２２ｃと、Ｘ線管２１ａを支持し、Ｘ線管２１ａを移動させる移動機構と、断続する複数回の撮影を行なうようにＸ線管及びＸ線検出器を制御するとともに、複数回の撮影のうち最初の撮影開始から最終の撮影終了までの間でＸ線管２１ａの移動速度が変化するように移動機構２４を制御してトモシンセシス撮影を実行するトモシンセシス撮影機能３１ｄと、を有する。【選択図】 図５
