Claim 12:
13. An ultrasound imaging system for generating ultrasound images with reduced speckle, the ultrasound imaging system comprising:
an ultrasound probe configured to generate ultrasound imaging data; and
one or more computing devices in communication with the ultrasound probe, the one or more computing devices configured to:
frequency compound the ultrasound image data from the ultrasound probe to generate frequency compounded ultrasound image data comprising a plurality of ultrasound images;
identifying a first portion of the plurality of ultrasound images from the frequency compounded ultrasound image data, the first portion having an angular displacement that exceeds a threshold angular displacement, wherein a second portion of the plurality of ultrasound images from the frequency compounded ultrasound image data does not exceed the threshold angular displacement;
selecting the one or more ultrasound images from the frequency compounded ultrasound image data based on the angular displacement exceeding the threshold angular displacement;
non-rigidly register the first portion of the plurality of ultrasound images from the frequency compounded ultrasound image data to generate registered ultrasound images; and
angle compound the registered ultrasound images to generate a compounded ultrasound image; and
output the compounded ultrasound image.
