Abstract

A method and system for acquiring, processing, storing, and displaying x-ray mammograms Mp tomosynthesis images Tr representative of breast slices, and x-ray tomosynthesis projection images Tp taken at different angles to a breast, where the Tr images are reconstructed from Tp images

Claims

1. A method of acquiring and displaying x-ray images comprising:

acquiring x-ray mammography image data Mp representative of projection mammography images of patients'"'"' breasts and x-ray tomosynthesis image data Tp representative of projection images Tp taken at different angles of an origin of imaging x-rays relative to the patients'"'"' breasts, from an acquisition unit configured to selectively acquire said mammography and tomosynthesis image data;

reconstructing at least a subset of the acquired Tp data into reconstructed tomosynthesis image data Tr representative of images of slices of the breasts that have selected orientations and thicknesses; and

displaying at least a selected subcombination of the Mp, Tr and Tp image data as respective Mp, Tp and/or Tr images for concurrent viewing while identifying the displayed images as Mp, Tr and/or Tp images.
