Claim Text:
1. A method for ultrasound aberration estimation, the method comprising: insonifying with first and second broad beams at first and second angles, respectively, from first and second excited transmit elements, the first and second broad transmit beams being diverging or unfocussed over an entire region of interest including a plurality of spatial locations; receiving first and second data sets of signals from a transducer, the receiving being in response to, respectively, the first and second excited transmit elements; focusing, by a receiver, the first and second data sets of the signals, the focusing resulting in first and second multi-dimensional images corresponding to the first and second broad beams, respectively, the first and second multi-dimensional images each representing the plurality of spatial locations; estimating an aberration as a function of comparing the first and second multi-dimensional images resulting from the receiver focusing; and correcting the first data set, the second data set, the first image, the second image, a subsequently received data set, or a subsequently focused image as a function of the aberration.
