Abstract
A synthetic aperture ultrasound system includes an ultrasound probe, and an ultrasound signal processor configured to communicate with the ultrasound probe to receive phase and amplitude information from a plurality of ultrasonic echo signals from a corresponding plurality of ultrasound pulses. The synthetic aperture ultrasound system also includes a positioning system configured to communicate with the ultrasound signal processor to provide probe position information. The positioning system is configured to determine a first position and a second position of the ultrasound probe relative to a region of interest. The ultrasound signal processor is further configured to coherently sum, utilizing the probe position information, at least one of the plurality of ultrasonic echo signals from the first position with at least one of the plurality of ultrasonic echo signals from the second position to provide a synthetic aperture that is larger than a physical aperture of the ultrasound probe.
