WebSeveral microbubble scattering models are highlighted (including the Rayleigh-Plesset model, the Rayleigh-Plesset-Noltingk-Neppiras-Poritsky model, the Herring model, the Marmottant model, and the non-spherical bubble dynamics model). The interaction between two microbubbles and the effect of radiation on the microbubbles is also discussed.
