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

1-121. -121. (canceled)

122. An image display system comprising:

a displayed image comprising at least one image of a plurality of tomosynthesis images of a compressed breast; and

a slider bar for identifying a height within the compressed breast corresponding to the displayed image, wherein the slider bar comprises a length; and

a slice bar movably positionable along the length of the slider bar, wherein a position of the slice bar along the length of the slider bar corresponds to a height of the displayed image within the compressed breast, wherein the slice bar comprises an adjustable thickness, and wherein a thickness of the slice bar corresponds to a thickness of the displayed image within the compressed breast.

129. An image display comprising:

at least one of a plurality of tomosynthesis images of a compressed breast;

a slider bar representative of a thickness of the compressed breast; and

a slice bar positionable along the slider bar, wherein a position of the slice bar corresponds to a position within the compressed breast of the displayed tomosynthesis image, and wherein a thickness of the slice bar corresponds to a thickness of the displayed tomosynthesis image.

136. A method of identifying select images in a plurality of tomosynthesis images, the method comprising:

displaying a slide bar;

displaying a slice bar on the slide bar;

applying a computer-aided detection algorithm to the plurality of tomosynthesis images;

identifying a select tomosynthesis image containing an area of interest, wherein the area of interest is identified by the application of the computer-aided detection algorithm;

displaying at least one of the plurality of tomosynthesis images; and

displaying a non-numeric indicia proximate the slide bar, wherein the non-numeric indicia corresponds to a position of the select tomosynthesis image within the plurality of tomosynthesis images.
