Angle Independent Ultrasonic Detection of Blood Flow

We present a new technique for blood velocity imaging based on tracking the motion of the speckle pattern produced by blood. Unlike Doppler velocity determinations, these are angle independent. Initial in vivo experiments yield promising results.
