Claim:
1. A system for displaying blood flow information concerning blood in a vessel, the system comprising: an ultrasound transducer that receives ultrasound signals; a controller that produces an ultrasound image of the vessel from the ultrasound signals, wherein the ultrasound image includes a representation of the vessel; a display that displays the ultrasound image; wherein the controller constructs and displays a user-positionable cursor overlaid over a sub-portion of the representation of the vessel in the displayed ultrasound image, and the user-positionable cursor identifies a single sub-sample volume of interest in the vessel; wherein the controller, for each of a plurality of different time intervals, determines a different true velocity vector of blood passing through the same single sub-sample volume located in the vessel from the ultrasound signals, and constructs a plurality of vector-markers, each vector-marker including a graphical indicator that indicates a magnitude and an angle of a different one of the true velocity vectors, wherein each of the graphical indicators includes an arrow with a line segment having a first end, a second opposing end, and a head disposed at the first end; and wherein the controller displays, concurrently, the arrows with the second ends at a same spatial point that is located within the same single sub-sample volume, wherein each of the arrows extends from the same point that is located within the same single sub-sample volume, and wherein the concurrently displayed plurality of the graphical indicators are concurrently visible.
