ABSTRACT:
A mammographic imaging system (1) is optimizd for use with a single fixed size flat panel digital image receptor (5). It accommodates compression devices (paddles) of varying sizes, and positions them properly in the field of view of the image receptor (5). When a compression paddle (2) with size smaller than the field of view of the image receptor is used, the compression paddle (2) can be shifted laterally in the direction parallel to the chest wall, so as to facilitate different views of different size breasts, and permit the image receptor to image as much of the desired tissue as possible. An automatic X-ray collimator (40) restricts the X-ray illumination (30) of the breast (3) in accordance with compression paddle (2) size and location in the field of view. An anti-scatter grid (4), mounted inside the image receptor enclosure, just below the top cover of the enclosure, can be retracted out of the field of view of the image receptor for use in magnification imaging.
