An X-ray diagnostics installation for mammography examinations has an arm
for an X-ray tube, a holder for an image receiver and a subject table. The
holder and the subject table are laterally adjustable relative to one
another. A compression plate arranged between the X-ray tube and the
subject table is connected to and displaceable along the arm. The arm is
rotatable around a horizontal shaft attached to a stand. In order to
maintain the image receiver located in the X-ray field simply and
inexpensively given rotation of the subject table or of the image receiver
from a vertical attitude into a lateral attitude, the holder for the image
receiver is connected to the arm, and the subject table is laterally
displaceable relative to the holder.
