System and method for generating a 2D image from a tomosynthesis data set
First Claim
1. A system for evaluating breast tissue, comprising:
- a processor configured toprocess a plurality of tomosynthesis projection images of a patient'"'"'s breast tissue to generate a plurality of tomosynthesis reconstructed images;
generate a tomosynthesis data set comprising one or more of the plurality of tomosynthesis projection images and/or one or more of the plurality of tomosynthesis reconstructed images;
analyze the tomosynthesis data set using computer aided detection (CAD); and
generate a two-dimensional synthesized mammogram from the tomosynthesis data set, wherein the synthesized mammogram comprises a synthesized two-dimensional image that simulates a conventional 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.
