Abstract: An X-ray diagnostics device for mammography examinations has an arm for an X-ray tube and a subject table as well as a compression plate arranged between the X-ray tube and the subject table, the compression plate being connected to the arm and being displaceable along it to compress a female breast. The arm is rotatable around a horizontal shaft, and the shaft is secured to a mount that is laterally displaceable. The mount is displaceably attached to a lifting arrangement connected to the stand that is height-adjustable. A control device accepts output signals from position sensors that indicate the height and lateral positions of the arm as well as from a synchro system that indicates the rotational angle of the arm, to control displacement arrangements the arm such that a rotation of the arm around an axis that can be arbitrarily selected along the longitudinal axis of the stand that is substantially aligned with the center axis of the compressed breast.

Abstract: An X-ray diagnostics device for mammography examinations has an arm for an X-ray tube and a subject table as well as a compression plate arranged between the X-ray tube and the subject table, the compression plate being connected to the arm and being displaceable along it. The arm can be rotated around a horizontal shaft and is height-adjustable along a longitudinal axis of a stand. The arm is rotatable with a first displacement arrangement around the horizontal shaft, and the shaft is secured to a mount that is laterally displaceable with a second displacement arrangement. As a result the arm is laterally displaceable. The mount is displaceably attached to a lifting arrangement connected to the stand, the lifting arrangement is height-adjustable with a third displacement arrangement.
