ABSTRACT:
The invention provides a digital x-ray mammography device capable of imaging a full breast. A movable aperture coupled with a movable x-ray image detector permits x-ray image data to be obtained with respect to partially overlapping x-ray beam paths from an x-ray source passing through a human breast. A digital computer programmed with a stitching algorithm produces a composite image of the breast from the image data obtained with respect to each path. In a preferred embodiment, a Schmidt camera images visible light produced at an x-ray to visible light conversion surface onto a digital detector array to produce an overlapping image pane with respect to each overlapping beam path.
