Abstract
A method for performing dual-energy x-ray imaging of a human breast including separating the breast image into five basic first order approximation image components: a dual-energy scatter image pair, a lean tissue image, a fat tissue image, and a microcalcification image. In the second order approximation, lean tissue image and fat tissue image are adjusted to correct for the microcalcification component so that each contains only a single breast component. The method also includes a calibration method so that the materials used are the actual breast tissues, instead of merely equivalent materials.
