1. A method for controlling an ultrasound system to produce one or more images to indicate a rate of perfusion of an anatomical region of interest (ROI) into which a contrast agent has been introduced, said method comprising the steps of:

  • a) deriving a first ultrasound image of said ROI and processing the ultrasound image to identify regions of the ROI that include contrast agent;

    b) assigning a first attribute to regions of the ROI identified in step a) as including contrast agent;

    c) repeating steps a) and b) to derive at least a second ultrasound image of said ROI and assigning a not previously assigned attribute to identified regions of the ROI that are identified as including contrast agent and have not previously had an attribute assigned thereto; and

    d) displaying an image that includes said ROI and respectively manifests said identified regions with said assigned attributes.
