Abstract
Very large, two-dimensional anisotropic arrays (also known as 1.5 dimensional arrays) have been proposed to enhance low contrast detectability for diagnostic ultrasound.1 These arrays are undersampled in the non-scan direction to reduce channel number. They are not suitable for real-time three-dimensional imaging due to limited steering capability in elevation. Nevertheless, they can provide full three-dimensional focus. Moreover, if used with a fully adaptive front-end, they can correct for beamforming artifacts associated with a large aperture.
