摘要：
Ultrasound imaging systems and methods for generated clutter-reduced images are provided. 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. Because off-axis signals are more likely to create image clutter, reducing the influence of off-axis signals on the image can therefore improve the quality of the image. Accordingly, embodiments of the present disclosure provide systems, methods, and devices for generating ultrasound images that have reduced or minimized clutter, even for images obtained using arrays that do not satisfy the Nyquist criterion.
