1. A method for providing real-time strain velocity images of a spatial region comprising:

  • firing ultrasound pulses into an area of interest of the spatial region;

    acquiring echo signals for a plurality of range positions along ultrasonic beams in an area of interest using a beam interleaving technique to acquire echo information along different beam directions during a time interval between two consecutive ultrasound pulse firings in a common direction;

    estimating, in real-time, strain velocities from said acquired echo signals for said range positions inside said spatial region; and

    displaying estimated strain velocities for each range position at spatial coordinates on a display unit associated with said spatial region to provide a real-time image of said strain velocities for said spatial region.
