SYSTEM AND METHOD FOR GENERATING A 2D IMAGE FROM A TOMOSYNTHESIS DATA SET

摘要

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.

1. A method for imaging breast tissue, comprising:
obtaining a plurality of tomosynthesis projection images; processing the plurality of tomosynthesis projection images to generate a plurality of tomosynthesis reconstructed images; analyzing a tomosynthesis data set comprising one or more of the plurality of tomosynthesis projection images and/or the plurality of tomosynthesis reconstructed images using computer aided detection (CAD); generating a two-dimensional synthesized mammogram from the tomosynthesis data set; and displaying the synthesized mammogram on a display device, wherein the synthesized mammogram comprises a synthesized two-dimensional image that simulates a conventional mammography image.
