Figure 2. Real-time longitudinal carotid artery scan at the bifurcation registered with a stored 3D US map with green cross markers.

Figure 2

Carotid US scan (left) co-registered to 3D map (right). Green crosses (circled) seen in both the left and right panel indicates that the scan plane was aligned with chosen features on the 3D map. The first cross, labeled with a 1, is located in the far wall of the internal carotid artery just superior to the bifurcation. The second marker, labeled with a 2, is located in the far wall of the common carotid artery about a centimeter inferior to the beginning of the bulb.
