Experimental results based on imaging of a wire target with: a plane wave imaging with one-way focusing. b Five-angle coherent compounding. c Two-way focusing. d ASI method. a–d Log-scaled magnitude images presented with −25 dB dynamic range. Axes are common to a–d. e Fourier transform of the focal depth line profile of the ASI pattern presented in Supplementary Fig. 3. f Pressure field-line profiles at the focal depth of 30 mm for a–d. g Fourier transform (k-space representation) of e
