Claim Text:
1. A mammography apparatus comprising: an x-ray source that emits an x-ray beam that comprises a central ray; a compression unit that compresses a breast therein with an adjustable compression pressure; a radiation detector; said x-ray source being mounted for movement along an arc-shaped trajectory so as to irradiate the breast in the compression unit with said x-ray beam from each of a plurality of different projection angles along said arc-shaped trajectory, and said radiation detector detecting x-rays that have proceeded through the breast in the compression unit at each of said projection angles, with said central ray proceeding through a different radioscopy path in the breast at the respective projection angles; and a control and evaluation unit configured to adjust the compression pressure applied to the breast by said compression unit to cause said radioscopy path of said central ray through the compressed breast to stay within a predetermined deviation, relative to a length of said radioscopy path at a first of said projection angles, as said x-ray source proceeds through said different projection angles along said arc-shaped trajectory.
