A tool navigation system employing an ultrasound imager (21), a tool tracker (41), a tissue classifier (50) and an image navigator (60). In operation, ultrasound imager (21) generates an ultrasound image of an anatomical region from a scan of the anatomical region by an ultrasound probe (20). As an interventional tool (40) is navigated within the anatomical region, the tool tracker (41) tracks a position of the interventional tool (40) relative to the anatomical region, tissue classifier (50) characterizes the tissue of the anatomical region adjacent the interventional tool (40), and image navigator (60) displays a navigational guide relative to a display of the ultrasound image of the anatomical region. The navigational guide illustrates a position tracking of the interventional tool (40) for spatial guidance of the interventional tool (40) within the anatomical region and further illustrates a tissue characterization of the anatomical region for target guidance of the interventional tool (40) to a target location within the anatomical region. |
