Experimental PSFs from the rotating arm device demonstrate sufficient calibration and mechanical precision to form high-resolution swept synthetic aperture images. (a) Single position fully-sampled synthetic aperture. (b) Swept synthetic aperture image from a 44.2 degree sweep. (c) Cystic resolution as a function of cyst radius based on the two PSFs. (d) Enlarged view of the location of the peak in each PSF subimage. The colored points represent the transducer position along the sweep path.
