Abstract

Displaying breast ultrasound information on an interactive user interface is described, the user interface being useful in adjunctive ultrasound mammography environments and/or ultrasound-only mammography environments. Bilateral comparison is facilitated by a pairwise display of thick-slice images corresponding to analogous slab-like subvolumes in the left and right breasts. Coronal thick-slice imaging and convenient navigation on and among coronal thick-slice images is described. In one preferred embodiment, a nipple marker is displayed the coronal thick-slice image representing a projection of a nipple location thereupon. A convenient breast icon is also displayed including a cursor position indicator variably disposed thereon in a manner that reflects a relative position between the cursor and the nipple marker. Preferably, the breast icon is configured to at least roughly resemble a clock face, the center of the clock face representing the nipple marker location. Bookmark-centric and CAD-marker-centric navigation within and among thick-slice images is also described.
