For example, an ultrasound imaging system can include an array of acoustic elements in communication with a processor. The processor is configured to activate the array to perform a scan sequence to obtain a plurality of signals, identify off-axis signals from the plurality of signals by comparing the right subaperture and the left subaperture, and create a clutter-reduced image based on the comparison.
