Abstract

Navigation among breast ultrasound volumes derived from different volumetric ultrasonic scans of a same breast is described. On a display of a breast ultrasound workstation, a first image derived from a first ultrasonic volume is displayed. A user election of a source region of interest (ROI) in the first image is received. A destination ROI within a second ultrasonic volume is identified that at least roughly corresponds to a same locality of tissue in the breast as the source ROI. A second image derived from the second ultrasonic volume and including the destination ROI is displayed, the destination ROI being highlighted.
