System and Method for Generating A 2D Image from a Tomosynthesis Data Set
First Claim
1. A method comprising:
- obtaining a plurality of x-ray tomosynthesis projection images of a patient'"'"'s breast;
synthesizing a two-dimensional mammogram by combining at least a subset of the plurality of x-ray tomosynthesis projection images using at least one of an algebraic method or a maximum intensity projection method; and
displaying the synthesized mammogram on a display device, wherein the synthesized mammogram refers to a synthesized 2D image that simulates a mammography image.

Abstract
A 2D mammogram image is synthesized from at least one of tomosynthesis projection images and/or the tomosynthesis reconstructed image data. In a simplest form, the mammogram may be synthesized by selecting one of the tomosynthesis projection images for display as a synthesized mammogram. Other methods of synthesizing a mammogram include re-projecting and filtering projection data and/or reconstructed data. The synthesized mammogram is advantageously displayed together with at least a portion of the reconstructed data to aid in review of the reconstructed data. The present invention thus provides a familiar image which may be used to facilitate review of a tomosynthesis data set.
