1. A method for imaging fluid flow in a target region, comprising the steps of:

  • transmitting a sequence of B-mode interrogating frames into the target region;

    receiving from the target region a sequence of B-mode echo frames corresponding to the sequence of B-mode interrogating frames;

    processing each B-mode echo frame to derive phase information for each location in the target region; and

    for each location in the target region, detecting changes in the phase information across multiple B-mode echo frames for detecting the presence of fluid flow at that location.
