Image handling and display in X-ray mammography and tomosynthesis
First Claim
Patent Images
1. A method of displaying x-ray image data comprising:
- acquiring two-dimensional x-ray projection images of a three-dimensional object obtained by using a tomosynthesis x-ray data acquisition unit that acquires each of the two-dimensional images by projecting an x-ray beam through the object at respective different angles of the beam relative to the object rather than by reconstructing a slice image;
reconstructing at least a portion of the acquired two-dimensional projection images into three-dimensional image data representing the three-dimensional object;
concurrently displaying on a display device (a) at least one of said two-dimensional projection x-ray images rather than images produced by reconstructing a slice image and (b) at least a portion of the three-dimensional reconstructed image data.

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.

6. A system for displaying x-ray image data comprising:
-
an x-ray tomosynthesis data acquisition system providing two-dimensional x-ray projection images of a three-dimensional object acquired by projecting an x-ray beam through the object at respective different angles of the beam relative to the object rather than by reconstructing slice images; a processor configured to reconstruct through computer processing at least a portion of the two-dimensional x-ray projection images into three-dimensional image data representing the three-dimensional object; and a computer display concurrently displaying (a) at least one of said two-dimensional x-ray projection images rather than images produced by reconstructing a slice image and (b) at least a portion of the three-dimensional reconstructed image data. - View Dependent Claims (7, 8, 9, 10)
