An improved x-ray mammography diagnostic apparatus with a digital detector forming a preferably rotatable subject table having a first concave curved surface formed by several arcs with different radii on one side of the table and another concave curved surface formed by several arcs with different radii on either adjacent or opposite side of the same table, these two curved surfaces allowing to accommodate curvature of the human breast and curvature of the rib cage below the breast of each patient and permitting to take a complete x-ray reading and detection of all areas of the human breast under examination, particularly at all points of connection with the rib cage wall and in the axilla area. The second concave curved surface is configured to fittingly accommodate the curvature of individuals with different bodily dimensions than those that could be accommodated by the first concave curved surface.
A mammogram recording and read-out apparatus comprises a radiation image detector having a rectangular shape, a detector support section, and a breast support section. A support state of the detector support section is capable of being changed over between a first support state, in which the radiation image detector is supported in an orientation such that a short side of the radiation image detector stands facing the chest wall of an object, and a second support state, in which the radiation image detector is supported in an orientation such that a long side of the radiation image detector stands facing the chest wall of the object.
