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.

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 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. - View Dependent Claims (19, 20)
