HIFU amplitude field in a lossless medium (water). The horizontal and vertical axes are respectively x and zÂaxes. Each image is normalized by maximum amplitude. (a)Numerical calculation via forward propagation using Rayleigh integral. (b) Experimental acquisition using backward reconstruction using Rayleigh integral. (c)Experimental acquisition using backward reconstruction using beamforming
