1. A method comprising:
- imaging a breast so as to acquire digital information corresponding to a plurality of 2D x-ray tomosynthesis projection images of the breast taken at different angles;
generating, from the digital information, a plurality of reconstructed tomosynthesis images representative of respective breast layers;
obtaining a 2D mammogram image of the breast; and
displaying at least one of the plurality of reconstructed tomosynthesis images representative of respective breast layers and the 2D mammogram image of the breast.

Abstract
A method and a system for using tomosynthesis projection images of a patient'"'"'s breast to reconstruct slice tomosynthesis images such that anatomical structures that appear superimposed in a mammogram are at conforming locations in the reconstructed images.

16. A method comprising:
-
displaying a tomosynthesis image representative of a layer of a breast; displaying a 2D mammogram image of the breast; and superimposing a marker on each of the displayed tomosynthesis image and the displayed 2D mammogram image, wherein the marker corresponds to a single predetermined location within the breast. - View Dependent Claims (17, 18, 19, 20)
