1. A system for imaging a breast of an upright patient with x-rays comprising:
a breast compression unit configured to compress a breast of an upright patient to different degrees at different angles relative to the breast;
an x-ray data acquisition unit configured to operate the system in a computerized tomography (CT) mode to thereby generate a plurality of CT x-ray projection images CTp of the breast taken at different angles; and
an image processing unit configured to computer-process the images CTp to thereby generate a three-dimensional reconstructed image CTr of at least a portion of the breast.
