Claim 30:
31. A non-transitory computer readable medium having stored thereon computer-readable instructions, that when executed by a processor causes the processor to perform the following:
capture, from an ultrasonic imaging device, data representative of a sequence of frames each comprising ultrasound imaging data representing an anatomical region of a human or animal subject at a respective different time;
analyze each frame in the captured data, to identify portions of the ultrasound imaging data, wherein the identified portions comprise both at least one single contrast element signal portion and at least one multiple contrast element signal portion, each single contrast element signal portion being representative of a contrast element wherein the contrast element comprises a microbubble and each multiple contrast element signal portion being representative of a plurality of contrast elements wherein the contrast elements comprise microbubbles;
assign a respective single position value to each of the single contrast element signal portions and assigning a respective single position value to each of the multiple contrast element signal portions; and
use a linking model that uses at least said assigned single position values for the single contrast element signal portion to link single contrast element signal portions represented in at least one of the frames to single or multiple contrast element signal portions represented in at least one other of the frames and that uses at least said assigned single position values for the multiple contrast element signal portions to link multiple contrast element signal portions represented in at least one of the frames to multiple contrast element signal portions represented in at least one other of the frames, thereby to track movement of contrast elements through said region of the subject.
