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