1. A method of tracking motion of a fluid with an imaging system comprising the steps of:
defining a region of interest containing fluid in motion with a controller of the imaging system;
transmitting a series of unfocused ultrasound pings into the region of interest from a transducer array of the imaging system;
receiving echoes from the series of unfocused ultrasound pings with a plurality of transducer elements of the transducer array;
identifying a fingerprint within the fiducial region, wherein the fingerprint comprises a pattern of data in the received echoes that is identifiable as a data string;
storing echo data received by each of the plurality of transducer elements in a separate memory string;
detecting movement of the fingerprint with the controller;
monitoring movement associated with a position of the identified fingerprint for as long as the pattern associated with the identified fingerprint is identifiable; and
communicating a signal with the controller indicating that movement of an object relative to the transducer array has occurred.
