MAMMOGRAPHY APPARATUS
FIG19 is a diagram illustrating an appropriate position of the top of the recess on the contact face in a case where the control circuit is disposed to be tilted
As shown in FIG19, this is similarly applied to a case where the control circuits disposed on the lower face 22 of the X-ray imaging panel 41, such as the first reading circuit 43A and/or the second reading circuit 43B, are disposed to be tilted inside the imaging stand 13. In this case, an interval between the line F1 and the line F2 becomes larger than that in a case where the control circuits disposed on the lower face 22 side of the X-ray imaging panel 41 are disposed to be parallel to the X-ray imaging panel 41 and the upper face 21 (see FIG19). As a result, it is possible to form the recess 35 to be large compared with a case where the control circuits disposed on the lower face 22 side of the X-ray imaging panel 41 are disposed to be parallel to the X-ray imaging panel 41 and the upper face 21, and thus, it is possible to reduce stress applied to the subject 60 by reducing pressurization of the abdomen 63 due to the imaging stand 13 in the CC imaging.

['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.']
