  • X-ray mammography apparatus with a compression plate that automatically adjusts to uniformly apply pressure
    Patent number: 6577703
    Abstract: An X-ray diagnostics apparatus for mammography examinations has an arm for an X-ray tube and a subject table and a compression plate arranged between the X-ray tube and the subject table. The compression plate is connected via a mount to the arm and is displaceable along the arm. The compression plate is connected to the mount so that the compression plate is rotatable relative to the subject table in the longitudinal and transverse directions of the plate. The examination apparatus generates a pressure against the breast under examination that is automatically uniformly distributed over the breast in an optimum way, by connecting the compression plate to the mount with at least one resilient connecting element in at least one connecting point.
