An adjunctive ultrasound mammography system and associated methods use an adjunctive ultrasound display configured for quick, intuitive, interactive viewing of volumetric ultrasound scans, displayed near a conventional x-ray mammogram display. Preferred navigations among a thick-slice image array, a selected enlarged thick-slice image, and planar ultrasound views are described, including a mode in which the planar ultrasound views are updated in real time as a cursor is moved across an active thick-slice image. In one example the thick-slice images are inverted prior to display, with non-breast areas of the image preferably segmented out and reset to dark. The inverted thick-slice images are of more familiar significance to radiologists as they are more like conventional x-ray mammograms and allow benign features to be more easily dismissed as compared to non-inverted thick-slice images. Preferred embodiments emphasize larger mass lesions and that compensate for mass lesions that straddle thick-slice region borders.

Adjunctive ultrasound processing and display for breast cancer screening

A method and system for processing and displaying breast ultrasound information is described. A 2D feature weighted volumetric coronal image as a 'guide' or 'road map' is generated from the 3D ultrasound data volume to represent the 3D dataset with the goal of emphasizing abnormalities within the breast while excluding non-breast structures, particularly those external to the breast such as ribs and chest wall.

Automated detection of suspected abnormalities in ultrasound breast images

Methods and related systems provide an interactive user interface in which CAD results are displayed in such a way that they may be used for both interpretation of detected abnormalities and for avoiding perceptual oversights. The output of a (multi-view) computer aided detection system is presented to the reader of a screening case in two phases: (1) an interactive phase, and (2) a prompting phase. In the first phase the reader can probe image locations for CAD information. In the second phase regions identified as relevant by the CAD system and not yet probed by the reader are prompted or displayed to the user, as these may have been overlooked by the reader. The CAD results can be calibrated to a probability of malignancy.
