1. An ultrasound imaging method, comprising:
transmitting a series of unfocused ultrasound tracking pings towards an object in a region of interest from one or more transmit elements of an ultrasound transducer array;
receiving echoes from the series of unfocused ultrasound tracking pings with a plurality of receive elements of the ultrasound transducer array;
identifying a pattern of data in raw un-beamformed data from the received echoes;
detecting movement of the pattern of data; and
indicating that movement of the pattern of data has occurred.
