Claim 20:
21. A method of generating an ultrasound image with reduced speckle, the method comprising:
frequency compounding ultrasound image data from an ultrasound probe to generate frequency compounded ultrasound image data comprising a plurality of ultrasound images;
tracking a region of interest being imaged between frames of the frequency compounded ultrasound image data to determine a spatial location of the region of interest;
computing a probe displacement of the ultrasound probe based on the determined spatial location of the region of interest;
controlling a phased array of the ultrasound probe to steer an ultrasound beam to the region of interest based on the computed probe displacement;
identifying an ultrasound image of the plurality of ultrasound images from the frequency compounded ultrasound image data, the ultrasound image having an angular displacement that exceeds a threshold angular displacement, wherein at least a portion of the plurality of ultrasound images from the frequency compounded ultrasound image data does not exceed the threshold angular displacement;
selecting the ultrasound image from the frequency compounded ultrasound image data based on the angular displacement exceeding the threshold angular displacement;
registering and angle compounding the selected ultrasound image with one or more other selected ultrasound images to generate a compounded ultrasound image; and
outputting the compounded ultrasound image.
