Abstract:
1. A method for displaying blood flow information concerning blood in a vessel, the method comprising: generating ultrasound signals by using an ultrasound transducer; producing, in electronic format, an ultrasound image of the vessel from the ultrasound signals, wherein the ultrasound image includes a representation of the vessel; displaying the ultrasound image via a display device; constructing and displaying a user-positionable cursor overlaid over a sub-portion of the representation of the vessel in the displayed ultrasound image, wherein the user-positionable cursor identifies a single sub-sample volume of interest in the vessel; obtaining, with a controller and for each of a plurality of different time intervals, a different true velocity vector of blood passing through the same single sub-sample volume located in the vessel wherein the true velocity vectors are determined from the ultrasound signals; constructing 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 linear line segment having a first end and a second opposing end and a head disposed at the first end; displaying, concurrently, the arrows with their 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 all of the concurrently displayed plurality of the graphical indicators are concurrently visible.
