Abstract:
1. A method for viewing mammography tomosynthesis images produced by an X-ray device, the method comprising: making several radiography projections of a body; reconstructing a digital volume of the body in slices; localizing structures representing radiology signs in the digital volume; computing for each localized radiology sign, a bounding surface corresponding to a surface demarcating a maximum extent of said radiology sign; determining for each bounding surface, a set of successive slices having a non-null intersection with said bounding surface; plotting a 2D contour about each intersection, in a corresponding reconstructed slice; and one of: continuously displaying the 2D contours of the slices of the digital volume in rapid succession on a screen for viewing; and applying a 3D viewing algorithm to the digital volume to produce the bounding surfaces.
