Abstract
Analytical expressions have been written for image quality in mammography. A multiparameter optimization has been conducted to find the mammography system requiring the lowest patient dose for a given image quality. The optimization is subject to constraints imposed by technology such as; power limits on tube focal spots, absorption efficiency related to detector resolution and others. The optimization permits system geometry, kVp, filtration, detector resolution, focal spot size and grid characteristics to vary simultaneously and self consistently subject to an exposure time constraint. Significant dose reductions compared to current mammography systems have been found without assuming radical technological advances.
