Quantitative flow imaging and data extraction.

<p>A) example slice position; B) example magnitude image with position of blood vessels marked on one side (ICA = internal carotid artery, JV = jugular vein, VA = vertebral artery); C) phase image at maximum arterial velocity; D) example velocity profiles of selected reference voxels in right ICA; E) resulting correlation map with positions of reference profiles marked; F) final vessel mask after thresholding of correlation map.
