    • A method for ultrasound imaging a target region with an ultrasound system having an ultrasound transducer array with a plurality of ultrasound elements thereon includes: (a) transmitting an ultrasound tracking beam from at least a subset of the plurality of elements of the array to the target region, each of the subset of the plurality of elements emitting a signal of the tracking beam with a respective transmission time shift; (b) receiving a plurality of echo signals at at least of the subset of the plurality of elements of the array, each echo signal being responsive to the tracking pulse; (c) applying the transmission time shift to at at least some of the subset of the respective plurality of elements to the plurality of echo signals received at corresponding ones of the plurality of elements; (d) modifying the transmission time shift and repeating steps (a)-(c) to provide an ultrasound dataset representing a recovered source element domain of the ultrasound dataset; (e) focusing and beamforming the ultrasound dataset to map time signals of the ultrasound dataset and combine channel signals to provide spatial pixel data; and (f) forming an ultrasound image from the spatial pixel data.
