Data from experiment and COMSOL Multiphysics simulation of an HIFU transducer operated at a frequence of 1MHz to observe the focus shift position caused by an acoustic liquid lens. Experiment: Images of the sound field created using Schlieren photography. Analysis of the images reveals the position of the focal point as well as the elliptical extent of the ablation zone. Simulation: Simulation of the acoustic pressure and heat transfer in the water phantom depending on the lens volume.
