MAMMOGRAPHY APPARATUS
FIG4 is a diagram illustrating an X-ray imaging panel or the like provided inside the imaging stand
The column 11 fixes the X-ray imaging unit or the like at a predetermined position in a predetermined direction on a floor face. The X-ray irradiation section 12 includes an X-ray tube that generates X-rays, and irradiates an X-ray imaging panel 41 (see FIG4) provided inside the imaging stand 13 with X-rays. As shown in FIG4, the imaging stand 13 includes the X-ray imaging panel 41, a switching circuit 42, a first reading circuit 43A, and a second reading circuit 43B.

['1. A mammography apparatus (10) comprising: an X-ray irradiation section (12) that irradiates an X-ray imaging panel (41) with X-rays; and an imaging stand (13) that includes the X-ray imaging panel and a control circuit (42, 43A, 43B) of the X-ray imaging panel, and is provided with an upper face (21) on which a breast of a subject is placed, a lower face (22) that is opposite to the upper face, a contact face (23) that is connected to the upper face and the lower face and comes in contact with a chest wall of the subject, a first side face (26A) and a second side face (26B) that are connected to the upper face, the lower face, and the contact face, and a recess (35) formed by cutting out at least a part of the contact face, wherein the recess has a shape in which among a first ridge portion (31) where the contact face and the upper face are connected to each other, a second ridge portion (32) where the contact face and the lower face are connected to each other, a third ridge portion (33) where the contact face and the first side face are connected to each other, and a fourth ridge portion (34) where the contact face and the second side face are connected to each other,  characterized in that  at least a part of the second ridge portion is cut out, and the first ridge portion, the third ridge portion, and the fourth ridge portion are not cut out.', '5. The mammography apparatus according to any one of claims 1 to 4, wherein a top of a boundary line between the recess and the contact face is disposed at the center between the first side face and the second side face, when seen from the contact face.', '13. The mammography apparatus according to any one of claims 1 to 12, wherein the recess in the contact face has a length that is equal to or larger than 15% of the X-ray imaging panel.']
