Comparison between high­speed camera observation and the position of the cavitation cloud calculated with the method based on three hydrophones. While the algorithm based on the full frequency bandwidth (red) gives an approximate position of the cavitation cloud, the one based on a bandwidth reduced around the subharmonic frequency (blue) give an enhanced localization of the cavitation cloud. The green circle denotes for the focal point of the US apparatus, used for the superimposition of the calculated position over the high­speed images
