Abstract: An x-ray mammography apparatus has a stereotactic biopsy unit having two holders for a biopsy needle, the holders extending parallel to the exposure plane. The free ends of the holders, in which the needle is retained, each have a releasable closure for the needle, so that the biopsy needle can be detached from the holder while remaining inserted in the breast. This permits the patient to be moved away from the mammography apparatus, for example into an operating room, with the needle remaining in place as a means for identifying the location for surgery.

Abstract: In an exemplary embodiment a compression carriage, adjustable by means of an electromotor, supports a compression localizer with which a switch is associated which disconnects the motor when the compression localizer engages the radiography subject. The connection between the motor and compression localizer can be selectively disengaged manually so as to allow manual movement of the compression localizer while the motor remains deenergized.

Abstract: The invention concerns an X-ray diagnostic apparatus with a motor-driven, vertically adjustable compression carriage, a means of support for a compression plate, and with a support plate for the object photographed. A means of support for a second closer to the focus, support plate and two support locations for the compression plate are provided, of which one is associated with the support plate which can receive the X-ray film cassette, and the other with the support plate which is closer to the focus.
