PROBLEM TO BE SOLVED: To acquire a higher quality of a photographed image by a mammographic apparatus.SOLUTION: A mammographic apparatus 2 includes an X-ray source 5, a detector 8 having a detection surface 8a for detecting an X-ray irradiated from the X-ray source 5, a first fixing member 7, and a second fixing member 11. The first fixing member 7 disposed between the X-ray source 5 and the detector 8 includes a first contact surface 7a that comes in contact with a breast and fixes it. The second fixing member 11 disposed between the first fixing member 7 and the X-ray source 5 includes a second contact surface facing the first contact surface 7a. At least one of the first contact surface 7a and the detection surface 8a includes a curved surface recessed on the opposite side to the X-ray source 5.SELECTED DRAWING: Figure 9COPYRIGHT: (C)2016,JPO&INPIT【課題】乳房画像撮影装置において、より品質のよい撮影画像を得る。【解決手段】乳房画像撮影装置2は、X線源5と、X線源5から照射されたX線を検出する検出面8aを有する検出器8と、第1固定部材7と、第2固定部材11とを備える。第1固定部材7は、X線源5と検出器8との間に配置され、乳房に接して固定するための第1当接面7aを有する。第2固定部材11は、第1固定部材7とX線源5との間に配置され、第1当接面7aに対向する第2当接面を有する。第1当接面7a及び検出面8aの少なくとも1つは、X線源5と反対側へ凹む曲面を含む。【選択図】図9
