Model fits to measured cavitation bubble dynamics in fibrin gels. Model-predicted cavitation bubble dynamics using the best parameter fits and experimental data points in fibrin hydrogels. (a) 2.5 mg mL⁻¹ fibrin gel with model fits generated for pulse energies E_p = 12 µJ (R_max = 126 µm, η = 20 kPa, ε_f,rr = 0.25, ε_f,θθ = 0.21) and E_p = 18 µJ (R_max = 156 µm, η = 23 kPa, ε_f,rr = 0.25, ε_f,θθ = 0.20). (b) 10 mg mL⁻¹ fibrin gel model predictions estimated from E_p = 12 µJ (R_max = 113 µm, η = 42 kPa, ε_f,rr = 0.23, ε_f,θθ = 0.18) and E_p = 18 µJ (R_max = 145 µm, η = 36 kPa, ε_f,rr = 0.27, ε_f,θθ = 0.23). The bubble dynamics model predictions are shown by the dashed curves while the experimental data are shown by the symbols. ○ and × symbols correspond to cavitation dynamics produced by laser pulse energies of E_p = 12 and 18 µJ, respectively.
