First Claim
Patent Images
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 concurrently or by toggling at least a selected combination of the Mp and Tr, or Mp and Tp, or Tr and Tp image data using a selected hanging protocol.

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.

15. A system comprising:
-
an acquisition unit comprising a breast platform, a source of x-rays at one side of the platform and an x-ray imaging device at another side of the platform, said acquisition unit selectively acquiring x-ray mammography image data representative of projection mammography images Mp of patients'"'"' breasts on said platform and x-ray tomosynthesis image data representative of tomosynthesis projection images Tp taken at different angles of at least the x-ray source relative to the breast platform; an image reconstruction unit coupled with the acquisition unit and receiving said image data therefrom and selectively reconstructing at least a subset of the acquired Tp images into reconstructed tomosynthesis images Tr representative of slices of the breasts that have selected orientations and thicknesses; and a display unit displaying concurrently or by toggling at least a selected combination or subcombinations of the Mp and Tr, or Mp and Tp, or Tr and Tp images for viewing according to a selected hanging protocol. - View Dependent Claims (16, 17)

18. A method of displaying x-ray images comprising:
-
providing x-ray data representative of at least one of (i) tomosynthesis images Tp representative of projection images taken at different angles of an origin of imaging x-rays relative to a patients'"'"' breasts, and (ii) reconstructed images Tr reconstructed from selected sets or subsets of said images Tp; wherein said images Tr are representative of slices of the breasts that have selected orientations and thicknesses; and selectively displaying stereoscopically selected pairs of at least two of said images Tp or at least two of said images Tr; including selectively providing images Tr that conform to a first set of imaging planes that are parallel to each other but are at different depth in a patient'"'"'s breast and a second set of images Tr that also are parallel to each other but are at different depths in the patient'"'"'s breast, where the two sets of imaging planes are angled to each other, and selectively scrolling through pairs of stereoscopically displayed Tr images, each pair comprising one Tr image from each set. - View Dependent Claims (19)
