Patent ID: 8234923

Claim:
An ultrasound imaging method comprising: obtaining and storing ultrasound data by, for each of a plurality of sources of ultrasound: transmitting ultrasound into a medium from the source of ultrasound; receiving and sampling signals resulting from interaction of the ultrasound with the medium at each of a plurality of receiving elements; and storing the sampled signals; and processing the ultrasound data to provide an image by: selecting a first subset of the stored sampled signals for which a first criterion relating to a location of at least one of the corresponding source and receiving element is satisfied and generating a first image from the first subset of the stored sampled signals; and selecting a second subset of the stored sampled signals for which a second criterion relating to a location of at least one of the corresponding source and receiving element is satisfied and generating a second image from the second subset of the stored sampled signals; and combining the first and second images to yield a display image.
