Modelling Lipid-Coated Microbubbles in Focused Ultrasound Applications at Subresonance Frequencies

Modelling Lipid-Coated Microbubbles in Focused Ultrasound Applications at Subresonance Frequencies

We present a computational study of the behaviour of a lipid-coated SonoVue microbubble with initial radius 1 µm ≤ R0 ≤ 2 µm, excited at frequencies (200–1500 kHz) significantly below the linear resonance frequency and pressure amplitudes of up to 1500 kPa—an excitation regime used in many applicati...
