HIFU amplitude field with aberrations obtained experimentally. Each image is normalized by maximum amplitude. (a) WideÂview image obtained by backward reconstruction using Rayleigh integral. (b) WideÂview image obtained by backward reconstruction using beamforming. (c) Reference image obtained by hydrophone measurements in the ROI of 8 × 20 mm2. (d) Reconstructed image via Rayleigh integral in the ROI. (e) Reconstructed image via beamforming in the ROI
