Effects of shell properties on the inertial cavitation threshold of a 1 μm lipid-coated microbubble (a–c) with and (d–f) without considering the inter-bubble interactions with a large lipid-coated bubble (R₂₀ = 5 μm). Threshold mapping with (a,d) variation of the initial surface tension and the elasticity of shells, (b,e) variation of the initial surface tension and the viscosity of shells and (c,f) variation of the shell elasticity and the shell viscosity. The inter-bubble distance is 20 μm.
