(a) K-space description (−20 dB contour) and (b) simulated PSF for a single aperture position. Slices from axial and lateral k-space are shown in gray. (c) K-space description (individual in gray and summed in black) and (d) PSF for five aperture positions, rotating the transducer about the target point with overlap. The larger lateral k-space extent provides improved lateral resolution of the point target, while overlapping regions provide an improved signal-to-noise ratio. (e) Lateral slice through PSF at the focus (100 mm).
