A digital mammography device includes an x-ray source (40) for approximating a point source at a breast (49), an aperture (45) and a digital x-ray detector (54). A positioning system positions the aperture and a digital x-ray detector (54) in harmony to provide overlapping x-ray beam paths so as to generate digital imaging data representing overlapping breast regions. A digital computer (72) programmed with stitching algorithm computes an image of a full breast from the overlapping breast regions. A positioning system positions two apertures and two detectors to provide overlapping regions. A CCD array (63) comprising a flat CsI scintillator (55) serves as the detector. |
